Political factions within parties emerge primarily due to ideological differences, divergent interests, or competing priorities among members. As political parties evolve, various groups may form around specific issues, such as environmental policy, economic management, or social justice. These factions can lead to internal debates that influence party direction and strategy, sometimes resulting in power struggles. Additionally, the emergence of factions can reflect broader societal trends or shifts, as party members align themselves with particular movements, affecting unity and cooperation in legislative actions.
