The next Polish uprising, the January 1863 Uprising, led to a further influx of Polish political exiles to Britain. Among them were people like Walery Wróblewski and the only notable Polish anarchist and follower of Bakunin, Walery Mroczkowski, member of the First Internationale and opponent of Marxist ideology. Polish Jews also fled due to the intensifying anti-Semitic pogroms and better economic opportunities. Among the notable Polish Jews who came to England were Henry Lowenfeld theatrical impresario and brewer, Michael Marks (co-founder of Marks & Spencer), Morris Wartski (founder of Wartski antique dealers) and the family of Jack Cohen, the founder of Tesco.
