Brazil's newly-elected President Dilma Rousseff is a Macedonian, according to a Facebook group that has emerged after media-craze in Bulgaria regarding Dilma's Bulgarian lineage.

Apart from the responsibility of governing one of the worlds biggest countries and most important advanced emerging economies, Dilma Rousseff will now probably have to face the worry of just which South-East European nation she actually belongs to, as the Macedonian Facebook group appears confident about knowing more about Dilma's origin that she knows herself.

Dilma's father Petar Rousseff was born in 1900 in the Bulgarian town of Gabrovo, and then emigrated to Brazil in the 1940s, where he settled and founded a family.

This has provoked the extraordinary interest of Bulgarian media, some of which are writing that Brazil has now something of a Bulgarian President.

The newly-appeared Facebook group, called "Dilma Rusev vistinska makedonka" ("Dilma Rousseff is a True Macedonian") has only 54 members at present but might well grow to tremendous proportions.

The hometown of Rousseff's father, Gabrovo, is in central Northern Bulgaria and nowhere close to the Bulgarian region bordering Macedonia (so-called Pirin Macedonia).

Since becoming an independent state in 1991, the ex-Yugoslav republic of Macedonia has had a number of protracted historical disputes with neighboring Bulgaria and Greece, in particular about the Macedonian or non-Macedonian nationality of a number of historical figures. Among them are Alexander the Great and Tsar Samuil (997-1014), whom Bulgarians recognize as one of their great Medieval rulers.
