Imperial Russian Army

Wars	Notable commanders

The Imperial Russian Army was the army of the Russian Empire, active from 1721 until the Russian Revolution of 1917. It was organized into a standing army and a state militia. The standing army consisted of regular troops and two forces that served on separate regulations: the Cossack troops and the Muslim troops.
A regular Russian army existed before the end of the Great Northern War in 1721. During his reign, Peter the Great accelerated the modernization of Russia's armed forces, including with a decree in 1699 that created the basis for recruiting soldiers, military regulations for the organization of the army in 1716, and creating the College of War in 1718 for the army administration. Starting in 1700 Peter began replacing the older Streltsy forces with new Western-style regiments organized on the basis of his already existing Guards regiments.
After the Napoleonic Wars the active Russian Army was maintained at just over 1 million men, which was increased to 1.7 million during the Crimean War. It remained at around this level until the outbreak of World War I, at which point Russia had the largest peacetime standing army in Europe, about 1.3 million. The wartime mobilization increased this to a strength of 4.5 million, and in total 15 million men served from 1914 to 1917.
In March 1917 the Imperial Army swore loyalty to the Russian Provisional Government after the abdication of Emperor Nicholas II, though the official status of the monarchy was not resolved until September 1917, when the Russian Republic was declared. Even after the February Revolution, despite its ineffectiveness on the offensive, the majority of the army remained intact and the troops were still at the front lines. The "old army" did not begin disintegrating until early 1918.

Precursors: Regiments of the New Order

before Peter the Great maintained professional hereditary musketeer corps known as streltsy. These were originally raised by Ivan the Terrible; originally an effective force, they had become highly unreliable and undisciplined. In times of war, the armed forces were augmented by peasants.
The regiments of the new order, or regiments of the foreign order, was the Russian term that was used to describe military units that were formed in the Tsardom of Russia in the 17th century according to the Western European military standards.
There were different kinds of regiments, such as the regulars, dragoons, and reiters. In 1631, the Russians created two regular regiments in Moscow. During the Smolensk War of 1632–1634, six more regular regiments, one reiter regiment, and a dragoon regiment were formed. Initially, they recruited children of the landless boyars and streltsy, volunteers, Cossacks and others. Commanding officers comprised mostly foreigners. After the war with Poland, all of the regiments were disbanded. During another Russo-Polish War, they were created again and became a principal force of the Russian Army. Often, regular and dragoon regiments were manned with datochniye lyudi for lifelong military service. Reiters were manned with small or landless gentry and boyars' children and were paid with money for their service. More than a half of the commanding officers were representatives from the gentry. In times of peace, some of the regiments were usually disbanded.
In 1681, there were 33 regular regiments and 25 dragoon and reiter regiments. In the late 17th century, regiments of the new type represented more than a half of the Russian Army and at the beginning of the 18th century were used for creating a regular army.

Introduction of conscription

was introduced by Peter the Great in December 1699, though reports say Peter's father also used it. The conscripts were called "recruits". They were not volunteers.
Peter formed a modern regular army built on the German model, but with a new aspect: officers not necessarily from nobility, as talented commoners were given promotions that eventually included a noble title at the attainment of an officer's rank. Conscription of peasants and townspeople was based on quota system, per settlement. Initially, it was based on the number of households, later it was based on the population numbers.
The term of service in the 18th century was for life. In 1793, it was reduced to 25 years. In 1834, it was reduced to 20 years plus five years in the reserve, and in 1855 to 12 years plus three years in the reserve.

1760s–1790s

The history of the Russian Army in this era was principally linked to the name of Russian General Alexander Suvorov, considered to be one of the few great generals in history who never lost a battle.
From 1777 to 1783 Suvorov served in the Crimea and in the Caucasus, becoming a lieutenant-general in 1780, and general of infantry in 1783, on the conclusion of his work there. From 1787 to 1791 he again fought the Turks during the Russo-Turkish War of 1787–1792 and won many victories. Suvorov's leadership also played a key role in a Russian victory over the Poles during the Kościuszko Uprising.

Imperial Russian Army in 1805

As a major European power, Russia could not escape the wars involving Revolutionary France and the First French Empire, but as an adversary to Napoleon, the leadership of the new emperor, Alexander I of Russia, who came to the throne as the result of his father's assassination became crucial.
The Russian Army in 1805 had many characteristics of Ancien Régime organization: there was no permanent formation above the regimental level, senior officers were largely recruited from aristocratic circles, and the Russian soldier, in line with 18th-century practice, was regularly beaten and punished to instill discipline. Furthermore, many lower-level officers were poorly trained and had difficulty getting their men to perform the sometimes complex manoeuvres required in a battle. Nevertheless, the Russians did have a fine artillery arm manned by soldiers trained in academies and who would regularly fight hard to prevent their pieces from falling into enemy hands.
Both the Russians and Austrians met a decisive military defeat at the hands of Napoleon during the Battle of Austerlitz in 1805.

Napoleonic Wars

The War of the Fourth Coalition involving Prussia, Russia, Saxony, Sweden and the United Kingdom against France formed within months of the collapse of the previous coalition. In August 1806, King Frederick William III of Prussia made the decision to go to war independently of any other great power except neighbouring Russia. Another course of action might have involved declaring war the previous year and joining Austria and Russia. This might have contained Napoleon and prevented the Allied disaster in the Battle of Austerlitz. In any event, the Russian Army, an ally of Prussia, still remained far away when Prussia declared war.
Napoleon smashed the main Prussian armies at the Battle of Jena–Auerstedt on 14 October 1806 and hunted down the survivors during the remainder of October and November. Having destroyed all Prussian forces west of the Oder, Napoleon pushed east to seize Warsaw. In late December, the initial clashes between the French and Russians at Czarnowo, Golymin, and Pułtusk were without result. The French emperor put his troops into winter quarters east of the Vistula River, but the new Russian commander Levin August von Bennigsen refused to remain passive.
Bennigsen shifted his army north into East Prussia and launched a stroke at the French strategic left wing. The main force of the blow was evaded by the French at the Battle of Mohrungen in late January 1807. In response, Napoleon mounted a counterattack designed to cut off the Russians. Bennigsen managed to avoid entrapment and the two sides fought the Battle of Eylau on 7 and 8 February 1807. After this indecisive bloodbath both sides belatedly went into winter quarters. In early June, Bennigsen mounted an offensive that was quickly parried by the French. Napoleon launched a pursuit toward Königsberg but the Russians successfully fended it off at the Battle of Heilsberg. On 14 June, Bennigsen unwisely fought the Battle of Friedland with a river at his back and saw his army mauled with heavy losses. Following this defeat, Alexander was forced to sue for peace with Napoleon at Tilsit on 7 July 1807, with Russia becoming Napoleon's ally. Russia lost little territory under the treaty, and Alexander made use of his alliance with Napoleon for further expansion. Napoleon created the Duchy of Warsaw out of former Prussian territory.
At the Congress of Erfurt Napoleon and Alexander agreed that Russia should force Sweden to join the Continental System, which led to the Finnish War of 1808–1809 and to the division of Sweden into two parts separated by the Gulf of Bothnia. The eastern part became the Russian Grand Duchy of Finland.
The Russo-Turkish War broke out in 1805–06 against the background of the Napoleonic Wars. The Ottoman Empire, encouraged by the Russian defeat in the Battle of Austerlitz, deposed the Russophile hospodars of its vassal states Moldavia and Wallachia. Simultaneously, their French allies occupied Dalmatia and threatened to penetrate the Danubian principalities at any time. In order to safeguard the Russian border against a possible French attack and support the First Serbian uprising, a 40,000-strong Russian contingent advanced into Moldavia and Wallachia. The Sultan reacted by blocking the Dardanelles to Russian ships in 1807 and declared war on Russia. The war lasted until 1812.
In the Finnish War Alexander wrested the Grand Duchy of Finland from Sweden in 1809, and acquired Bessarabia from Turkey in 1812.

Anglo-Russian War (1807–1812)

The requirement of joining France's Continental Blockade against Britain was a serious disruption of Russian commerce, and in 1810 Alexander repudiated the obligation. This strategic change was followed by a substantial reform in the army undertaken by Michael Andreas Barclay de Tolly as the Minister of War.
At the same time, Russia continued its expansion. The Congress of Vienna created the Kingdom of Poland, to which Alexander granted a constitution. Thus, Alexander I became the constitutional monarch of Poland while remaining the autocratic Emperor of Russia. He was also the Grand Duke of Finland, which had been annexed from Sweden in 1809 and awarded autonomous status.
The Russo-French alliance gradually became strained. Napoleon was concerned about Russia's intentions in the strategically vital Bosphorus and Dardanelles straits. At the same time, Alexander viewed the Duchy of Warsaw, the French-controlled reconstituted Polish state, with suspicion. The result was the War of the Sixth Coalition from 1812 to 1814.
