What is a quaker and what impact did this group have on the establishment of Pennsylvania

A Quaker is is someone one practices a specific religion (a sect of Christianity). They are known for being against all forms of violence. This is called being a pacifist. They usually don't have priests or ministers and believe in worshiping in their own way. They followed William Penn (who Pennsylvania is named after) and settled in a new colony. The Quakers helped establish a new government. They also protected the rights of Native Americans and were abolitionists (meaning they didn't believe in slavery because slavery often involves violence which went against their beliefs).
