The Crimean War (October 1853 – February 1856) was a conflict in which Russia lost to an alliance of France, the United Kingdom, the Ottoman Empire, and Sardinia. The immediate cause involved the rights of Christian minorities in the Holy Land, which was controlled by the Ottoman Empire. The French promoted the rights of Catholics, while Russia promoted those of the Eastern Orthodox Christians. The longer-term causes involved the decline of the Ottoman Empire and the unwillingness of the United Kingdom and France to allow Russia to gain territory and power at Ottoman expense. It has widely been noted that the causes, in one case involving an argument over a key, have never revealed a "greater confusion of purpose", yet led to a war noted for its "notoriously incompetent international butchery."
While the churches eventually worked out their differences and came to an initial agreement, both Nicholas I of Russia and Napoleon III refused to back down. Nicholas issued an ultimatum that the Orthodox subjects of the Empire be placed under his protection. Britain attempted to mediate, and arranged a compromise that Nicholas agreed to. When the Ottomans demanded changes, Nicholas refused and prepared for war. Having obtained promises of support from France and Britain, the Ottomans officially declared war on Russia in October 1853.
The internationally recognised Ukrainian territory of Crimea was annexed by the Russian Federation on 18 March 2014. From the time of the annexation, Russia has de facto administered the peninsula as two federal subjects—the Republic of Crimea and the city of Sevastopol—within the Crimean Federal District. The military intervention and annexation by Russia took place in the aftermath of the Ukrainian Revolution and was part of wider unrest across southern and eastern Ukraine. On 22–23 February, Russian President Vladimir Putin convened an all-night meeting with security services chiefs to discuss extrication of the deposed Ukrainian president, Viktor Yanukovych, and at the end of that meeting Putin had remarked that "we must start working on returning Crimea to Russia." On 23 February pro-Russian demonstrations were held in the Crimean city of Sevastopol. On 27 February masked Russian troops without insignias took over the Supreme Council of Crimea, and captured strategic sites across Crimea, which led to the installation of the pro-Russian Aksyonov government in Crimea, the holding of a disputed, unconstitutional referendum and the declaration of Crimea's independence.
