How do countries change their government?

Countries can change their government through various means, including democratic elections, where citizens vote to select new leaders or political parties. Additionally, revolutions or uprisings may lead to a complete overhaul of the existing government structure, often in response to widespread dissatisfaction. Some nations might also experience coups, where military or political factions seize control without popular consent. Constitutional amendments or reforms can also facilitate changes in government, allowing for shifts in power dynamics or governance structures.
