Wilhelm II was the last German Emperor. His bold signature, often written “Wilhelm I.R.” (Imperator Rex), appears on commissions, award patents and signed photographs, and is one of the most sought-after of the period, with an equally large market in facsimiles.

Who Was Kaiser Wilhelm II?

Wilhelm II was born in Berlin in 1859 and became German Emperor and King of Prussia on 15 June 1888. In March 1890 he forced the resignation of Chancellor Otto von Bismarck. On 4 August 1914 he called for national unity in the Reichstag; from 1916 his influence over the conduct of the war declined as Hindenburg and Ludendorff led the Supreme Army Command.

What Documents Bear II’s Signature?

His signature appears on officers’ commissions, award patents, letters and photographs, and on correspondence from his exile at Doorn. Many printed patents carry a facsimile signature. Heads of state and senior officials did not sign everything issued in their name: printed and stamped facsimiles, secretarial signatures and signatures “by order” are common on routine documents. See original signature or facsimile.

What Should Collectors Watch For?

  • “Wilhelm I.R.” marks his reign; exile signatures differ.
  • Printed facsimiles on patents and postcards are very common.
  • Signed photographs from exile were produced in numbers; check provenance.

Abdication and Exile

Chancellor Max von Baden announced his abdication on 9 November 1918; the next day Wilhelm fled from Spa to the Netherlands and signed the formal abdication on 28 November. From 1919 he lived at Haus Doorn, where he died in 1941.

Collector’s Note

“Wilhelm I.R.” is one of the great signatures of the 20th century. I check every example against the line quality of authenticated exemplars, because the facsimiles are excellent.
