Abd al-Qadir ibn Muhyi al-Din (6 September 1808 - 26 May 1883) 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.
