## Introduction

By the Treaty of Hamburg (1701), most of the Mecklenburg territory went to Mecklenburg-Schwerin. (...) The Congress of Viena in 1814-15 recognised it as grand duchy (...). The Nationalsocialist government in 1934 merged it with Mecklenburg-Strelitz into one Land.

Grand Duke's house flag: Stander der Grossherzoglichen residenzgebaude wenn dort geflaggt wird, ohne dass Mitglieder des Grossherzoglichen Hauses dort Wohnung genommen haben, hausgenommen Heiligendamm eingefuhrt. [Pennant of the grand ducal residence buildings when they are decorated with flags, when no members of the grand ducal family are living there, first hoisted when the Heiligendamm was put in use.]

Jaume Ollé, 27 September 1998, translated by Santiago Dotor, 28 September 2000

## Proposals of Carl Wilhelm Theremin 1848

Proposal no.1 (see left image above) was a vertical black-red-golden tricolour. On canton on the black stripe was a blue-white-red horizontal tricolour.
Proposal no.2 (see right image above) was a blue-white-red horizontal tricolour with golden canton parted by a black centred cross fimbriated red on the top stripe.
According to Jan Schlürmann the blue-white-red tricolour had not been related to Mecklenburg-Schwerin, but it hd been the ensign (Seeflagge) of the city of Rostock instead.
