Invasion of Algiers in 1830 in the context of "July Revolution"

Algeria, officially the People's Democratic Republic of Algeria, is a country in the Maghreb region of North Africa. It is bordered to the northeast by Tunisia; to the east by Libya; to the southeast by Niger; to the southwest by Mali, Mauritania, and Western Sahara; to the west by Morocco; and to the north by the Mediterranean Sea. The capital and largest city is Algiers, located in the far north on the Mediterranean coast.

Algeria has been at the crossroads of numerous cultures and civilisations for millennia, including the Phoenicians, Numidians, Romans, Vandals, and Byzantine Greeks. Its modern identity is rooted in centuries of Arab Muslim migration since the seventh century and the subsequent Arabisation of indigenous Berber populations. Following a succession of Islamic Arab and Berber dynasties between the eighth and 15th centuries, the Regency of Algiers was established in 1516 as a largely independent tributary state of the Ottoman Empire. After nearly three centuries as a major power in the Mediterranean, the country was invaded by France in 1830 and formally annexed in 1848, though it was not fully conquered and pacified until 1903. French rule brought mass European settlement that displaced the local population, which was reduced by up to one-third due to warfare, disease, and starvation. The Sétif and Guelma massacre in 1945 catalysed local resistance that culminated in the outbreak of the Algerian War in 1954. Algeria gained independence in 1962. It descended into a bloody civil war from 1992 to 2002, remaining in an official state of emergency until the 2010–2012 Algerian protests during the Arab Spring.

Algiers is the capital city of Algeria, located on the Mediterranean Sea in the north-central portion of the country. In 2025, an estimated 4.325 million people resided within the urban area. Algiers is the largest city in Algeria, the third-largest city on the Mediterranean, the sixth-largest city in the Arab world, and the 29th-largest city in Africa by population. Algiers is the capital of the Algiers Province; it extends over many communes without having its own separate governing body. It extends along the Bay of Algiers surrounded by the Mitidja Plain and major mountain ranges. Its favorable location made it the center of Ottoman and French influences for the region, shaping it to be a diverse metropolis.

Algiers was formally founded in 972 AD by Buluggin ibn Ziri, though its history goes back to between 1200 and 250 BC as a Phoenician trading settlement. Over time, it came under the control of several powers, including Numidia, the Roman Empire, and various Islamic caliphates. In 1516, it became the capital of the Ottoman Regency of Algiers, a status it held until the French invasion in 1830, after which it served as the capital of French Algeria. During World War II, it briefly functioned as the administrative center of Free France from 1942 to 1944 before returning to French colonial rule. It has remained the capital of the modern Algerian state since the Algerian Revolution in 1962.

The Algerian popular resistance against French invasion refers to resistance in Algeria against the French conquest, which began with the invasion of Algiers in 1830 and lasted until 1903.

Abd al-Qadir ibn Muhyi al-Din (6 September 1808 – 26 May 1883; Arabic: عبد القادر ابن محي الدين ʿAbd al-Qādir ibn Muḥy al-Dīn), known as the Emir Abdelkader or Abd al-Qadir al-Hassani al-Jaza'iri, was an Algerian religious and military leader who led a struggle against the French colonial invasion of Algiers in the early 19th century. As an Islamic scholar and Sufi who unexpectedly found himself leading a military campaign, he built up a collection of Algerian tribesmen that for many years successfully held out against one of the most advanced armies in Europe.

His consistent regard for what would now be called human rights, especially as regards his Christian opponents, drew widespread admiration, and a crucial intervention to save the Christian community of Damascus from a massacre in 1860 brought honours and awards from around the world. Within Algeria, he was able to unite many Arab and Berber tribes to resist the spread of French colonization. His efforts to unite the country against French invaders led some French authors to describe him as a "modern Jugurtha", and his ability to combine religious and political authority has led to his being acclaimed as the "Saint among the Princes, the Prince among the Saints".

Admiral of France Guy-Victor Duperré (20 February 1775 – 2 November 1846) was a French Navy officer. He is known for commanding French naval forces in the Mauritius campaign of 1809–1811 and was victorious in the Battle of Grand Port, where he was wounded. Later he had a command in the Mediterranean and continued to serve during and after the Bourbon Restoration. He commanded the naval elements of the expeditionary force that carried out the Invasion of Algiers in 1830 and went on to become Minister of the Navy three times.
