He was the eldest son of Emperor Paul I and Sophie Dorothea of Württemberg. The son of Grand Duke Paul Petrovich, later Paul I, Alexander succeeded to the throne after his father was murdered.

Greek War of IndependenceThe Greek War of Independence, also known as the Greek Revolution or the Greek Revolution of 1821, was a successful war of independence by Greek revolutionaries against the Ottoman Empire between 1821 and 1829. In 1826, the Greeks were assisted by the British Empire, Kingdom of France, and the Russian Empire, while the Ottomans were aided by their North African vassals, particularly the eyalet of Egypt. The war led to the formation of modern Greece, which would be expanded to its modern size in later years.
Concert of EuropeThe Concert of Europe was a general consensus among the great powers of 19th-century Europe to maintain the European balance of power, political boundaries, and spheres of influence. Never a perfect unity and subject to disputes and jockeying for position and influence, the Concert was an extended period of relative peace and stability in Europe following the Wars of the French Revolution and Napoleonic Wars which had consumed the continent since the 1790s. There is considerable scholarly dispute over the exact nature and duration of the Concert.
Regency eraThe Regency era of British history is commonly applied to the years between 1795 and 1837, although the official regency for which it is named only spanned the years 1811 to 1820. King George III first suffered debilitating illness in the late 1780s, and relapsed into his final mental illness in 1810; by the Regency Act 1811, his eldest son George, Prince of Wales, was appointed prince regent to discharge royal functions. When George III died in 1820, the Prince Regent succeeded him as George IV.

United Kingdom of Great Britain and IrelandThe United Kingdom of Great Britain and Ireland was a sovereign state in Northwestern Europe that comprised the entirety of the British Isles between 1801 and 1922. It was established by the Acts of Union 1800, which merged the Kingdom of Great Britain and the Kingdom of Ireland into a unified state.
