Northwestern Europe in the context of "Matres and Matronae"

Ireland is an island in the North Atlantic Ocean, in Northwestern Europe. Geopolitically, the island is divided between the Republic of Ireland (officially named Ireland – a sovereign state covering five-sixths of the island) and Northern Ireland (part of the United Kingdom – covering the remaining sixth). It is separated from Great Britain to its east by the North Channel, the Irish Sea, and St George's Channel. Ireland is the second-largest island of the British Isles, the third-largest in Europe, and the twentieth-largest in the world. As of 2022, the population of the entire island is just over 7 million, with 5.1 million in the Republic of Ireland and 1.9 million in Northern Ireland, ranking it the second-most populous island in Europe after Great Britain.

The geography of Ireland comprises relatively low-lying mountains surrounding a central plain, with several navigable rivers extending inland. Much of Ireland was woodland until the end of the Middle Ages. Today, woodland makes up about 10% of the island, compared with a European average of over 33%, with most of it being non-native conifer plantations. Its lush vegetation is a product of its mild climate, which is influenced by the Atlantic Ocean and thus very moderate, and winters are milder than expected for such a northerly area, although summers are cooler than those in continental Europe. Rainfall and cloud cover are abundant.

The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a country in Northwestern Europe, off the coast of the continental mainland. It comprises England, Scotland, Wales and Northern Ireland, with a population of over 69 million in 2024. The UK includes the island of Great Britain, the north-eastern part of the island of Ireland, and most of the smaller islands within the British Isles, covering 94,354 square miles (244,376 km). It shares a land border with the Republic of Ireland and is otherwise surrounded by the Atlantic Ocean, the North Sea, the English Channel, the Celtic Sea and the Irish Sea, while maintaining sovereignty over the British Overseas Territories. The capital and largest city of both England and the UK is London; Edinburgh, Cardiff and Belfast are the national capitals of Scotland, Wales and Northern Ireland.

Britain has been inhabited since the Neolithic. In AD 43 the Roman conquest of Britain began. The Roman departure between 383 and 410 was followed by Anglo-Saxon settlement beginning around 450. In 1066 the Normans conquered England. After the Wars of the Roses, the Kingdom of England began to flourish, resulting in the 16th-century annexation of Wales and the establishment of the British Empire. Over the 17th century the role of the British monarchy was reduced, particularly as a result of the English Civil War. In 1707 the Kingdom of England and the Kingdom of Scotland united under the Treaty of Union to create the Kingdom of Great Britain. In the Georgian era the office of prime minister became established. The Acts of Union 1800 incorporated the Kingdom of Ireland to create the United Kingdom of Great Britain and Ireland in 1801. Most of Ireland seceded from the UK in 1922 as the Irish Free State, and the Royal and Parliamentary Titles Act 1927 created the present United Kingdom.

Ireland (Irish: Éire [ˈeːɾʲə] ), also known as the Republic of Ireland (Poblacht na hÉireann), is a country in Northwestern Europe. It consists of 26 of the 32 counties of the island of Ireland, with a population of about 5.4 million. Its capital and largest city is Dublin, on the eastern side of the island, with a population of over 1.5 million. The sovereign state shares its only land border with Northern Ireland, which is part of the United Kingdom. It is otherwise surrounded by the Atlantic Ocean, with the Celtic Sea to the south, St George's Channel to the south-east and the Irish Sea to the east. It is a unitary, parliamentary republic. The legislature, the Oireachtas, consists of a lower house, Dáil Éireann; an upper house, Seanad Éireann; and an elected president (Uachtarán) who serves as the largely ceremonial head of state, but with some important powers and duties. The head of government is the Taoiseach (prime minister, lit. 'chief'), elected by the Dáil and appointed by the president, who appoints other government ministers.

The Irish Free State was created with Dominion status in 1922, following the Anglo-Irish Treaty. In 1937, a new constitution was adopted, in which the state was named "Ireland" and effectively became a republic, with an elected non-executive president. It was officially declared a republic in 1949, following The Republic of Ireland Act 1948. Ireland became a member of the United Nations in 1955. It joined the European Communities (EC), the predecessor of the European Union (EU), in 1973. The state had no formal relations with Northern Ireland for most of the 20th century, but the 1980s and 1990s saw the British and Irish governments working with Northern Irish parties to resolve the conflict that had become known as the Troubles. Since the signing of the Good Friday Agreement in 1998, the Irish government and Northern Irish government have co-operated on a number of policy areas under the North/South Ministerial Council created by the Agreement.

The Kingdom of the Netherlands, commonly known simply as the Netherlands, is a sovereign state consisting of a collection of constituent territories united under the monarch of the Netherlands, who functions as head of state. The realm is not a federation; it is a unitary monarchy with its largest subdivision, the eponymous Netherlands, predominantly located in Northwestern Europe and with several smaller island territories located in the Caribbean.

The four subdivisions of the Kingdom—Aruba, Curaçao, the Netherlands, and Sint Maarten—are constituent countries (landen in Dutch; singular: land) and participate on a basis of equality as partners in the Kingdom. In practice, however, most of the Kingdom's affairs are administered by the Netherlands—which comprises roughly 98% of the Kingdom's land area and population—on behalf of the entire Kingdom. Consequently, Aruba, Curaçao, and Sint Maarten are dependent on the Netherlands for matters like foreign policy and defence, but are autonomous to a certain degree, with their own parliaments.

Belgium, officially the Kingdom of Belgium, is a country in Northwestern Europe. Situated in a coastal lowland region known as the Low Countries, it is bordered by the Netherlands to the north, Germany to the east, Luxembourg to the southeast, France to the south, and the North Sea to the west. Belgium covers an area of 30,689 km (11,849 sq mi) and has a population of more than 11.8 million; its population density of 383/km (990/sq mi) ranks 22nd in the world and sixth in Europe. The capital and largest metropolitan region is Brussels; other major cities are Antwerp, Ghent, Charleroi, Liège, Bruges, Namur, and Leuven.

Belgium is a parliamentary constitutional monarchy with a complex federal system structured on regional and linguistic grounds. The country is divided into three highly autonomous regions: the Flemish Region (Flanders) in the north, the Walloon Region (Wallonia) in the south, and the Brussels-Capital Region in the middle. Belgium is also home to two main linguistic communities: the Dutch-speaking Flemish Community, which constitutes about 60 percent of the population, and the French-speaking French Community, which constitutes about 40 percent of the population; a small German-speaking Community, comprising around one percent of the population, exists in the East Cantons. Belgium's linguistic diversity and related political conflicts are reflected in its complex system of governance, made up of six different governments. Belgium is a developed country with an advanced high-income economy. It is one of the six founding members of the European Union, with its capital of Brussels serving as the de facto capital of the EU, hosting the official seats of the European Commission, the Council of the European Union, the European Council, and one of two seats of the European Parliament (the other being Strasbourg). Brussels also hosts the headquarters of many major international organizations, such as NATO.

The Netherlands is a country in Northwestern Europe, with overseas territories in the Caribbean. It is the largest of the four constituent countries of the Kingdom of the Netherlands. The Netherlands consists of twelve provinces; it borders Germany to the east and Belgium to the south, with a North Sea coastline to the north and west. It shares maritime borders with the United Kingdom, Germany, and Belgium. The official language is Dutch, with West Frisian as a secondary official language in the province of Friesland. Dutch, English, and Papiamento are official in the Caribbean territories. People from the Netherlands are referred to as Dutch.

Netherlands literally means "lower countries", in reference to its low elevation and flat topography, 26% of which is below sea level. Most of the areas below sea level, known as polders, are the result of land reclamation that began in the 14th century. In the Republican period, which began in 1588, the Netherlands entered a unique era of political, economic, and cultural greatness, ranked among the most powerful and influential in Europe and the world; this period is known as the Dutch Golden Age. During this time, its trading companies, the Dutch East India Company and the Dutch West India Company, established colonies and trading posts all over the world. While neutral in the First World War, the Netherlands was invaded and occupied by Nazi Germany in 1940 during the Second World War, which lasted until the end of the war in 1945.

The Indo-Aryan languages, or sometimes Indic languages, are a branch of the Indo-Iranian languages in the Indo-European language family. As of 2024, there are more than 1.5 billion speakers, primarily concentrated east of the Indus River in Bangladesh, Northern India, Eastern Pakistan, Sri Lanka, Maldives and Nepal. Moreover, apart from the Indian subcontinent, large immigrant and expatriate Indo-Aryan–speaking communities live in Northwestern Europe, Western Asia, North America, the Caribbean, Southeast Africa, Polynesia and Australia, along with several million speakers of Romani languages primarily concentrated in Southeastern Europe. There are over 200 known Indo-Aryan languages.

Modern Indo-Aryan languages descend from Old Indo-Aryan languages such as early Vedic Sanskrit, through Middle Indo-Aryan languages (or Prakrits). The largest such languages in terms of first-speakers are Hindustani (Hindi/Urdu) (c. 330 million), Bengali (242 million), Punjabi (about 150 million), Marathi (112 million), and Gujarati (60 million). A 2005 estimate placed the total number of native speakers of the Indo-Aryan languages at nearly 900 million people. Other estimates are higher, suggesting a figure of 1.5 billion speakers of Indo-Aryan languages.

The territory today known as England became inhabited more than 800,000 years ago, as the discovery of stone tools and footprints at Happisburgh in Norfolk have indicated. The earliest evidence for early modern humans in Northwestern Europe, a jawbone discovered in Devon at Kents Cavern in 1927, was re-dated in 2011 to between 41,000 and 44,000 years old. Continuous human habitation in England dates to around 13,000 years ago (see Creswellian), at the end of the Last Glacial Period. The region has numerous remains from the Mesolithic, Neolithic and Bronze Age, such as Stonehenge and Avebury. In the Iron Age, all of Britain south of the Firth of Forth was inhabited by the Celtic people known as the Britons, including some Belgic tribes (e.g. the Atrebates, the Catuvellauni, the Trinovantes, etc.) in the south east. In AD 43 the Roman conquest of Britain began; the Romans maintained control of their province of Britannia until the early 5th century.

The end of Roman rule in Britain facilitated the Anglo-Saxon settlement of Britain, which historians often regard as the origin of England and of the English people. The Anglo-Saxons, a collection of various Germanic peoples, established several kingdoms that became the primary powers in present-day England and parts of southern Scotland. They introduced the Old English language, which largely displaced the previous Brittonic language. The Anglo-Saxons warred with British successor states in western Britain and the Hen Ogledd (Old North; the Brittonic-speaking parts of northern Britain), as well as with each other. Raids by Vikings became frequent after about AD 800, and the Norsemen settled in large parts of what is now England. During this period, several rulers attempted to unite the various Anglo-Saxon kingdoms, an effort that led to the emergence of the Kingdom of England by the 10th century.
