フォンテーヌブローの勅令
After the French king Louis XIV declared Protestantism illegal in 1685 in the Edict of Fontainebleau, an estimated 50,000 Protestant Huguenots fled to England. Due to sustained and sometimes mass emigration of the Irish, current estimates indicate that around 6 million people in the UK have at least one grandparent born in the Republic of Ireland.
