Why was the petition written by pennsylvania german quakers in 1688 significant?

The Quakers and the petition were the pioneers in the fight against slavery in the Thirteen Colonies.

Explanation:

Indeed, the Quakers were the pioneers in the fight against slavery in the Thirteen Colonies. Actually, they had been debating each other for a long time. William Penn himself, founder of the Pennsylvania colony in 1682, had argued in his day that slavery was acceptable as long as the slave owners duly met their material and spiritual needs. Among the Quakers, as a reflection of what would later happen in the general sphere, there was an obvious struggle between greed and intense humanism regarding this issue, eventually defeating the latter. George Keith and his followers clearly stated the immorality of slavery. In this sense, it was published in 1673, An Exhortation and Caution To Friends Concerning Buying or Selling of Negroes. It can be considered the first text against slavery in North America. A few years later, in 1688 a group of German Quakers and Mennonites, gathered in Germantown, made public their opposition to human trafficking.
