Political parties first To nominate presidential candidates?

Political parties began nominating presidential candidates in the early 19th century, with the Democratic-Republican Party being one of the first to establish a formal nomination process. The practice became more organized with the advent of national conventions in the 1830s, where delegates would gather to select their party's nominee. The modern primary system evolved later in the 20th century, allowing party members to vote directly for their preferred candidates. Today, nominations are a key aspect of the electoral process, reflecting party ideology and voter preferences.
