Stamp Giveaway Series 2, # 21 [solved]

Michelangelo (Grenada souvenir sheet; Ajman set and souvenir sheet; Manama set and souvenir sheet)

A European controlled area was divided into a colony and various protected jurisdictions. Two of the protected jurisdictions asked to have post offices subordinate to the one in the colony. Soon thereafter the colony's stamps had a major design change, resulting in complaints from the two protected areas. An agreement among the colony and the protected areas called for a postal union recognizing the validity of the stamps of each jurisdiction in all three jurisdictions. How long did it take for stamps of the complaining protected areas to be issued?

The winning response will be the first to mention the correct time period and received at or before 10 AM eastern US time July 2, 2022. If no correct response is received, the winner will be the first to name all 3 jurisdictions. If no one names the 3 jurisdictions, the winner will be the first to name a single jurisdiction. If no one names a single jurisdiction, the winner will be the first to mention the year the protected areas asked for subordinate post offices. My decision as to the winner will be final.

Competition is open to everyone. Good luck to all who choose to participate!

I'll leave a wild guess of 6 months to 1 year.

I'm totally clueless about the area, it may be in Africa or Southeast Asia.

Let's wait and see what the others can find.

Sounds like something that could have happened in South Africa around the time of the Boer war. So I guess 5 years for the war and another 5 years for British bureaucracy  so that gives a decade.

Looks like a clue is needed. Before getting its own stamps the colony was considered part of British India.

I propose Jammu and Kashmir : 

Although the first stamp on march 1866 was issued for both, there were then separate issues until 1878, twelve years later, when common stamps were issued again.

Can't believe I stumped you guys. The prize for this competition will be held over for the next as no one came close in their guesses.

The crown colony of Aden separated from British India in 1937 and got its own stamps. In the same year the sultans of Seiyun and Qu'aiti states in the Aden Protectorate asked for post offices to be established. In 1939 the Aden colony issued stamps picturing King George VI. Seiyun and Qu'aiti complained since their residents were not British subjects under the rule of the British king. This led to the postal union being agreed but due to World War II stamps picturing the sultans were not issued until 1942.

Watch for the next competition.
