The Crimean War was a military conflict fought from October 1853 to February 1856 in which Russia lost to an alliance of France, the Ottoman Empire, the United Kingdom and Sardinia. The immediate cause of the war involved the rights of Christian minorities in the Holy Land, which was part of the Ottoman Empire. The French promoted the rights of Roman Catholics, and Russia promoted those of the Eastern Orthodox Church. Longer-term causes involved the decline of the Ottoman Empire and the unwillingness of Britain and France to allow Russia to gain territory and power at the expense of the Ottoman Empire. It has widely been noted that the causes, in one case involving an argument over a key, had never revealed a "greater confusion of purpose" but led to a war that stood out for its "notoriously incompetent international butchery".

The Macedonian rebellion of 1854 took place in 1854 and is divided into two phases: the first phase took place in Western and Southern Macedonia and the second in Chalkidiki. However, after pressure from the United Kingdom and France on the government of King Otto of Greece, he was forced to recall the chieftain taking part in the rebellions throughout the Greek-inhabited regions of the Ottoman Empire, including Macedonia. The governments of the United Kingdom and France had assumed that the rebellions were related to the Crimean War (1854–1856).

The two Ad hoc Divans were legislative and consultative assemblies of the Danubian Principalities, vassals of the Ottoman Empire. They were established by the Great Powers under the Treaty of Paris.

Officially, the two assemblies were provisional replacements for the traditional assemblies, the Sfaturi. The term "divan", is derived from the Ottoman rule, being the name of a high governmental body in a number of Islamic states.

The Charge of the Light Brigade was a failed military action involving the British light cavalry led by Lord Cardigan against Russian forces during the Battle of Balaclava on 25 October 1854 in the Crimean War. Lord Raglan had intended to send the Light Brigade to prevent the Russians from removing captured guns from overrun Turkish positions, a task for which the light cavalry were well-suited. However, there was miscommunication in the chain of command and the Light Brigade was instead sent on a frontal assault against a different artillery battery, one well-prepared with excellent fields of defensive fire. The Light Brigade reached the battery under withering direct fire and scattered some of the gunners, but they were forced to retreat immediately, and the assault ended with very high British casualties and no decisive gains.
