Alexei Mikhailovich ascended the Russian throne in 1645 at age sixteen, inheriting a realm that would expand to nearly 8.1 million square kilometres by the time of his death. As the second monarch of the House of Romanov, he centralized authority by becoming the first tsar to issue laws exclusively under his own sovereign mandate.
Early Governance and Legal Reform
Initially mentored by the boyar Boris Morozov, the young tsar faced immediate social volatility. Economic strain caused by tax increases led to the 1648 Salt Riot in Moscow, forcing the exile of his tutor. In response to civil unrest, Alexei codified the legal standards of his realm with the 1649 Sobornoye Ulozheniye, a document that formally aligned the interests of the autocracy with the lower nobility.
Military Modernization
In 1648, the Tsar initiated a systematic restructuring of the armed forces by developing New Order Regiments. These units, which included soldiers, dragoons, and hussars, relied on the expertise of European specialists recruited following the conclusion of the Thirty Years' War. This professionalized force provided the necessary capability for the Tsar to pursue aggressive territorial expansion against neighbouring powers.

Alexei presided over significant wars against Poland, Sweden, and Safavid Iran. His campaigns resulted in the annexation of Smolensk and left-bank Ukraine, bolstered by the Treaty of Pereyaslav. While his foreign policy achieved territorial gains, these efforts burdened the national economy, leading to the 1662 Copper Riot after attempts to inflate revenue through currency devaluation failed.
Internal Rebellions
Beyond metropolitan riots, the crown faced sustained provincial opposition. Uprisings occurred in Pskov and Great Novgorod during 1650. The most substantial challenge originated in the south during 1669, when the Cossack Stenka Razin led an insurrection along the Volga River. Although the revolt successfully seized several towns, it was suppressed by 1671, resulting in the execution of the rebel leader in Moscow.
Church Schism
Religious life during the reign was defined by a profound schism within the Eastern Orthodox Church. Alexei maintained a close alliance with Patriarch Nikon, supporting the introduction of controversial liturgical reforms. These institutional changes caused lasting friction within the ecclesiastical structure of Russia.
