Context and question: The most notable difference is that, contrary to other European heraldic systems, the Jews, Muslim Tatars or another minorities would be given the noble title. Also, most families sharing origin would also share a coat-of-arms. They would also share arms with families adopted into the clan (these would often have their arms officially altered upon ennoblement). Sometimes unrelated families would be falsely attributed to the clan on the basis of similarity of arms. Also often noble families claimed inaccurate clan membership. Logically, the number of coats of arms in this system was rather low and did not exceed 200 in late Middle Ages (40,000 in the late 18th century).
Did number of cat of arms in the late middle ages fall?
Answer: low and did not exceed 200
Context and question: The Duke of York had required that every community in his new lands of New York and New Jersey support some church, but this was more often Dutch Reformed, Quaker or Presbyterian, than Anglican. Some chose to support more than one church. He also ordained that the tax-payers were free, having paid his local tax, to choose their own church. The terms for the surrender of New Amsterdam had provided that the Dutch would have liberty of conscience, and the Duke, as an openly divine-right Catholic, was no friend of Anglicanism. The first Anglican minister in New Jersey arrived in 1698, though Anglicanism was more popular in New York.
Why was the Duke not a friend of Anglicanism?
Answer: openly divine-right Catholic,
