In mid-November 1866 the Maximilian government lost control of the Guadalajara district to the hands of the Republicans. At the beginning remainders of 1856 - 1861 and sellos negros (stampless mail) were used. Once the stamps were about to be depleted, provisional stamps were issued. This issue was in place until the next general issue came about in September 8th, 1868, more than one year after the Emperor's execution.
