Political parties
In Great Britain, political parties were historically referred to as "factions" or "clubs," particularly during the 17th and 18th centuries. These terms highlighted the informal and often localized nature of political organization before the modern party system emerged. The term "orders" was used in some contexts, but it was less common. Over time, these factions evolved into more structured political parties, such as the Whigs and Tories, laying the groundwork for the contemporary political landscape.
