A political party is an organization that coordinates candidates to compete in elections and participate in governance. It is common for the members of a party to hold similar ideas about politics, and parties may promote specific ideological or policy goals.
Political parties have become a major part of the politics of almost every country, as modern party organizations developed and spread around the world over the last few centuries. Although some countries have no political parties, this is extremely rare. Most countries have several parties while others only have one. Parties are important in the politics of autocracies as well as democracies, though usually democracies have more political parties than autocracies. Autocracies often have a single party that governs the country, and some political scientists consider competition between two or more parties to be an essential part of democracy.
