Hans Adam Dorten (10 February 1880 – April 1963) was a German career lawyer who in 1919 became a separatist leader in the militarily occupied Rhineland, following German defeat in the First World War.The period was a confused one during which political objectives were not always firmly fixed, nor clearly set out, but it is understood that Dorten's preference was for a Rhineland separated from "protestant" Prussia, and economically more closely aligned with France.
At the end of 1923, a final attempt to establish an independent Rhenish state having failed, he escaped to Nice in France: here he resumed his legal career and worked on his memoirs.
