Cabinda

Formerly Portuguese Congo, this territory had protectorate status since 1883 and was separate from Portuguese West Africa. As part of various independence movements in the 1960s a group called Front for the Liberation of the Enclave of Cabinda (FLEC) established a government-in-exile in Kinshasa. FLEC made a unilateral declaration of independence on 1 August 1975 but it was not recognised by Portugal or internationally.
In November 1975, Angolan troops of the MPLA occupied Cabinda which was annexed into the newly independent Angolan state. Angola calls the territory Cabinda Province. Since then, FLEC and other factions within Cabinda have struggled for full independence and seek to form the Republic of Cabinda.
Various organizations have issued stamps for Cabinda (widely regarded as cinderellas). These include:

• The Cabinda National Philatelic Bureau, which issued a set of eleven overprints on Angolan stamps, all with a denomination of 500 Central African francs, with designs showing fauna and mushrooms on 27 October 2006. These stamps have seen some use as paquebot mail in theCarribean.
• The Federation of Free States of Africa, which issued thirty one designs showing the coat of arms and flag as well as ships, fauna, planes, natives and a map of Africa from 2010 to 2012.
• Other stamps and miniature sheets for thematic collectors appeared on eBay, Delcampe and other websites from sellers in Belarus, France, Israel and the United States.

Madiera

Thanks Radim, finally Madiera!!!!!

On 1 January 1868, Portugal issued postage stamps for the islands of Madeira, consisting of the current stamps of Portugal overprinted"MADEIRA". Subsequent stamps were also overprinted, through 1881.

The first stamps inscribed for Madeira were part of the Vasco da Gama Issue of 1898. Subsequently Madeira used stamps of Portugal, with two exceptions; the first was the Pombal Issue of postal tax stamps in 1925, and a variant on the Ceres design, issued 1 May 1928. The 21 values of Ceres stamps were obligatory on all mail for eight days - 1 May, 5 June, 1 July, and 31 December 1928, and 1 January, 31 January, 1 May, and 5 June 1929. The funds raised went to help build a museum.

The Ceres stamps were the last to be produced for Madeira until 1980, when Portugal began issuing stamps inscribed "Portugal Madeira" that were valid in both Madeira and continental Portugal, similar to those issued for the Azores.
