Boundaries between the continents in the context of "Sultan of the Ottoman Empire"

Europe is a continent located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south, and Asia to the east. Europe shares the landmass of Eurasia with Asia, and of Afro-Eurasia with both Africa and Asia. Europe is commonly considered to be separated from Asia by the watershed of the Ural Mountains, the Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea, and the Turkish straits.

Europe covers approx. 10,186,000 square kilometres (3,933,000 sq mi), or 2% of Earth's surface (6.8% of Earth's land area), making it the second-smallest continent (using the seven-continent model). Politically, Europe is divided into about fifty sovereign states, of which Russia is the largest and most populous, spanning 39% of the continent and comprising 15% of its population. Europe had a total population of about 745 million (about 10% of the world population) in 2021; the third-largest after Asia and Africa. The European climate is affected by warm Atlantic currents, such as the Gulf Stream, which produce a temperate climate, tempering winters and summers, on much of the continent. Further from the sea, seasonal differences are more noticeable producing more continental climates.

A continent is any of several large terrestrial geographical regions. Continents are generally identified by convention rather than any strict criteria. A continent could be a single large landmass, a landmass and nearby islands either on or beyond its continental shelf, or a part of a larger landmass, as in the case of Asia and Europe within Eurasia. Due to these varying definitions, the number of continents varies, up to seven or as few as four. Most English-speaking countries recognize seven continents. In order from largest to smallest in area, these seven are Asia, Africa, North America, South America, Antarctica, Europe, and Australia (or sometimes Oceania or Australasia). Different variations with fewer continents merge some of these regions; examples of this are merging Asia and Europe into Eurasia, North America and South America into the Americas (or simply America), and Africa, Asia, and Europe into Afro-Eurasia.

Oceanic islands are occasionally grouped with a nearby continent to divide all the world's land into geographical regions. Under this scheme, most of the island countries and territories in the Pacific Ocean are grouped together with the continent of Australia to form the geographical region of Oceania.

The Caucasus (/ˈkɔːkəsəs/) or Caucasia (/kɔːˈkeɪʒə/) is a region spanning Eastern Europe and Western Asia. It is situated between the Black Sea and the Caspian Sea, comprising parts of Southern Russia, Georgia, Armenia, and Azerbaijan. The Caucasus Mountains, including the Greater Caucasus range, have conventionally been considered as a natural barrier between Europe and Asia, bisecting the Eurasian landmass. Mount Elbrus, Europe's highest mountain, is situated in the Western Caucasus area of Russia. On the southern side, the Lesser Caucasus includes the Javakheti Plateau and the Armenian highlands.

The Caucasus is divided into the North Caucasus and South Caucasus, although the Western Caucasus also exists as a distinct geographic space within the North Caucasus. The Greater Caucasus mountain range in the north is mostly shared by Russia and Georgia as well as the northernmost parts of Azerbaijan. The Lesser Caucasus mountain range in the south is mostly located on the territory of southern Georgia, Armenia, and Azerbaijan. The region is known for its linguistic diversity: aside from Indo-European and Turkic languages, the Kartvelian, Northwest Caucasian, and Northeast Caucasian language families are indigenous to the area.

Azerbaijan, officially the Republic of Azerbaijan, is a transcontinental and landlocked country at the boundary of Western Asia and Eastern Europe. It is a part of the South Caucasus region and is bounded by the Caspian Sea to the east, Russia's republic of Dagestan to the north, Georgia to the northwest, Armenia and Turkey to the west, and Iran to the south. Baku is the capital and largest city.

The territory of what is now Azerbaijan was ruled first by Caucasian Albania and later by various Persian empires. Until the 19th century, it remained part of Qajar Iran, but the Russo-Persian wars of 1804–1813 and 1826–1828 forced the Qajar Empire to cede its Caucasian territories to the Russian Empire; the treaties of Gulistan in 1813 and Turkmenchay in 1828 defined the border between Russia and Iran. The region north of the Aras was part of Iran until it was conquered by Russia in the 19th century, where it was administered as part of the Caucasus Viceroyalty.

This is a list of countries with territory that straddles more than one continent, known as transcontinental states or intercontinental states.

Contiguous transcontinental countries are states that have one continuous or immediately-adjacent piece of territory that spans a continental boundary, most commonly the line that separates Asia and Europe. By contrast, non-contiguous transcontinental countries are those states that have portions of territory that are separated from one another either by a body of water or by other countries (such as in the case of France). Most non-contiguous transcontinental countries are countries with dependencies like United Kingdom with its overseas territories, but can be countries that have fully integrated former dependencies in their central states like France with its overseas regions.

"European people" is an umbrella term for people who belong to any ethnic, racial, or national group with origins in Europe. Today, it primarily refers to people who are from Europe and reside in the continent, as well as the European diaspora. By extension, however, the term "European" may be applied to identify people in the context of demographics in certain countries outside of Europe—namely in the Americas and in Oceania—where people of European ancestry constitute the majority of the population while being part of a non-European national group. Additionally, any person who holds European Union citizenship may be identified as European in that particular context.

As of 2025, Europe's total population is estimated to be 744 million people, with nearly 87 million international migrants in 2020. Per a 2015 estimate, over 480 million people in countries outside of Europe have at least some European ancestry. Most indigenous Europeans are racially classified as White, which is also the most common term applied to people of European descent in non-European countries. Between the 18th and 20th centuries, a now-disproven race concept classified European people as part of the so-called Caucasian race, which broadly grouped together the populations of Europe, West Asia and North Africa, Central Asia, and South Asia. Although it is generally avoided in modern academic discourse, "Caucasian" is still used in official data for United States censuses to racially classify people whose ancestry or ethnicity is European, Middle Eastern, or North African.
