Key factors in the formation of political coalitions include shared interests, mutual benefits, and the desire to achieve common goals. Coalition-building often arises in contexts where no single party holds a clear majority, prompting partnerships across ideological divides to secure governance. Effective communication and negotiation skills are crucial for overcoming differences. Additionally, external pressures, such as electoral systems and public opinion, can motivate parties to collaborate. Successful coalitions can enhance political stability and facilitate more comprehensive policy-making within fragmented political landscapes.
