How many leaders has Sinn Fein had?

Sinn Féin has had two leaders in Northern Ireland since the party was established in its modern form in the 1970s. The first leader was Gerry Adams, who led the party from 1983 until 2018. He played a pivotal role in the peace process and the party's transformation into a political power in both Northern Ireland and the Republic of Ireland. The current leader, as of 2018, is Mary Lou McDonald, who has continued to advance the party's agenda for Irish reunification and social equality.

The number of leaders reflects the continuity and evolution of leadership within the party while maintaining its core identity and political goals over the decades. This context serves to highlight Sinn Féin's ability to adapt to changing political landscapes while remaining consistent in its overall objectives.
