What are Quakers called today?
The Quakers are still called Quakers. However, they prefer to be called 'Friends' and they are members of a family of religious movements called the "Religious Society of Friends".
The people who lived in Pennsylvania were called Quakers. It's pretty much just a group of Christian believers. :)The Quakers got their name because of what they do; quake. The Quakers weren't called Quakers until someone decided to make fun of them. When they prayed, they would sometimes rock back and forth or quake. When people started laughing and calling them "Quakers", they responded positively. They called themselves Quakers from then on.
There is not just 'was' about Quakers - we exist and thrive today. The questioner may get a better answer if the question can be made more explicit by saying what aspects of life s/he is interested in and what period, as Quakers have been around since the 1650's and different factors have been prominent in different times.
Society of friends protestant sect founded in 1640s in England whose members believed that salvation was available to all people?
Pennsylvania was settled by the Quakers. Quakers are known for their pacifistic views. The city Philidelphia is called the "city of brotherly love" I don't know exactly how the religion in Pennsylvania differenciated, but if there were others who believed differently, there was never any fighting because of the Quakers.
