Unification of Russian lands
The unification of the Russian lands ended under Ivan III's son, Vasily III, who ruled in Moscow from 1505 to 1533. In place of the disparate principalities, a large state of Russia appeared, spread over 2,800 thousand square kilometers. It was a single state, where all cities and lands were subordinate to the Grand Duke. The population of Russia was 9 million people. Previously, the appanage princes were the rulers of their lands, but now they have become the boyars of the Grand Duke and entered the Boyar Duma. It was a council of noble people who helped the prince solve important issues. The decrees said: "The Grand Duke ordered, and the boyars were sentenced." However, there were still traces of feudal fragmentation in the country. Some boyar princely states retained their possessions and felt like little rulers. They had their own squads and did not always obey Moscow. In the 16th century, the Moscow government fought against this in order to strengthen the central government. Before his death, Vasily III bequeathed the throne to his son Ivan, who was only three years old at the time. The state was ruled by his mother, Princess Elena, with her brothers, the Princes of Glinsky.
When Ivan grew up, disputes for power began. His uncles, the brothers of Vasily III, wanted to rule themselves, but the Glinskys defeated them and sent them to prison. But after Elena's death, the Shuisky princes seized power, then the Belsky. In 1546, the Glinskys returned to power.
These changes were often accompanied by violence and killings. The boyars who ruled the country used their power for personal gain.
Ivan IV, the future tsar Ivan the Terrible, witnessed all these events. He also sometimes intervened in the struggle for power. In 1543, he ordered the execution of Prince Andrei Shuisky, and in 1546– two princes Vorontsov. In January 1547, Ivan turned 17 years old, and he was crowned king in the Assumption Cathedral of the Kremlin. Metropolitan Macarius put a golden crown on him and proclaimed him an autocratic tsar. Ivan became the first tsar of Russia. This event strengthened his power and increased the international prestige of the country.
In February 1547, Ivan married Anastasia, the daughter of the Moscow boyar Roman Zakharin. From that moment on, he became an adult and could manage the state himself.
