Absolute monarchies were common during the Age of Absolutism from the 1500s to late 1700s. Absolute monarchs possessed total control over their kingdoms and had several advantages, such as efficient decision making and long-term stability. However, they also had weaknesses like being undemocratic and restricting individual rights. Russia in particular was isolated during this period due to Mongol rule and a lack of warm water ports, but Czars like Peter the Great sought to modernize and Westernize the nation through reforms like building the new capital St. Petersburg.
