Flag of the Cape Colony

The flag of Cape Colony was the official flag of the Cape Colony from 1876 to 1910. It formed part of a system of colonial flags that was used throughout the British Empire.

History
In a series of decisions made in 1864, 1865, and 1869, the UK's government decided that every colony should have a distinctive badge, to be displayed on flags at sea. The governor was to display the badge in the center of the Union Jack when travelling by sea; vessels owned by the colony's government were to display it in the fly of the Blue Ensign;  and, with Admiralty permission, privately owned ships registered in the colony could display the badge in the fly of the Red Ensign. This system is still in operation in the remaining British overseas territories.

The Cape government was initially not in favor of the system but eventually complied with British government requests to adopt a flag badge. The Molteno ministry decided to introduce a coat of arms, which would also serve as the flag badge. The coat of arms was first displayed on a flag at the laying of the foundation stone of the Houses of Parliament on 12 May 1875. It was formally granted by Queen Victoria on 29 May 1876, and made its official appearance as a flag badge shortly afterwards. It was used until the colony was incorporated into the Union of South Africa on 31 May 1910.

Description
The flag badge consisted of the Cape Colony coat of arms on a white disc. The coat of arms consisted of a red shield displaying a golden lion between three golden rings, below a silver horizontal strip ('chief') containing three golden fleurs de lis on blue discs. The figure of Hope formed the crest, and the shield was supported by a wildebeest and a gemsbok. The motto 'Spes Bona' ('Good Hope') was displayed below the shield.
