Pazardzhik Province in the context of "Sofia Province"

Pirin Macedonia or Bulgarian Macedonia (Bulgarian: Пиринска Македония; Българска Македония) (Pirinska Makedoniya or Bulgarska Makedoniya), which today is in southwestern Bulgaria, is the third-biggest part of the geographical region of Macedonia. This part coincides with the borders of Blagoevgrad Province, as well as the surrounding area of Barakovo from Kyustendil Province. After World War I, Strumica and the surrounding area were broken away from the region and were ceded to Yugoslavia.

It covers an area of about 6,798 km, which is 10.18% of the geographical region of Macedonia. One of the regional centers is Blagoevgrad. The region borders Kyustendil Province and Sofia Province to the north, Pazardzhik Province and Smolyan Province to the east, Greece to the south, and North Macedonia to the west. The population is estimated around 290,000 people.

Pazardzhik (Bulgarian: Пазарджик [ˈpazɐrd͡ʒik]) is a city situated along the banks of the Maritsa river, southern Bulgaria. It is the centre of Pazardzhik Province and Pazardzhik Municipality. It is located in the Upper Thracian Plain and in the Pazardzhik-Plovdiv Field, a subregion of the plains. It is west of Plovdiv, about 37 kilometres (23 mi), 112 kilometres (70 mi) southeast of Sofia and 288 kilometres (179 mi) from Burgas. The population is 55,220, as it has been growing around from the end of the 19th century to the end of the 20th century. The city reached its highest milestone, exceeding 80,000. Due to poor economic performance in Bulgaria during the 1990s and early 2000s, emigration of Bulgarians began, which affected Pazardzhik as well.

The history of Pazardzhik can be traced back to the 7th millennium BC, with early civilisations being brought from Asia-Minor. They were agro-pastralists and settled near Maritsa, Pazardzhik and Sinitovo. A clay idol named the Pazardzhik Venus was found in 1872. The Drougoubitai tribe settled in the early Middle Ages. Many different researches have all been disputed on the founding of Pazardzhik. One of them was that the city was founded in 1395 by nomads from Saruhan. Another one was three years later in 1398, the city was founded by the migration of Tatars from Actav to Rumelia. The third is about the establishment in 1418, where the Minnet Bey and the Tatars came from Isquilip, and the fourth thesis and the final one is the city's foundation from the resettled Crimean Tatar people. Rice cultivation intensified in the region, which made the economy of the city grow.

The Muslim Bulgarians (Bulgarian: Българи-мохамедани, romanized: Bǎlgari-mohamedani, lit. 'Bulgarian Mohammedans', as of recently also Българи-мюсюлмани, Bǎlgari-mjusjulmani, locally called Pomak, ahryan, poganets, marvak, or poturnak) are Bulgarians who follow the faith of Islam. They are generally thought to be the descendants of the indigenous Slavs who converted to Islam during Ottoman rule. Most scholars have agreed that the Bulgarian Muslims are a "religious group of Bulgarian Slavs who speak Bulgarian as their mother tongue and do not understand Turkish, but whose religion and customs are Islamic". Bulgarian Muslims live mostly in the Rhodopes – Smolyan Province, the southern part of the Pazardzhik and Kardzhali Provinces and the eastern part of the Blagoevgrad Province in Southern Bulgaria. They also live in a group of villages in the Lovech Province in Northern Bulgaria. The name Pomak is pejorative in Bulgarian and is resented by most members of the community, The name adopted and used instead of Pomak is Bulgarian Muslims.

Bulgarian Muslims do not represent a homogenous community and have a multitude of ethnic and religious identities. A clear majority of them (127,350 according to the latest census in 2001) declare themselves to be ethnic Bulgarians of Islamic faith. However, a significant percentage, in particular in the Central and Eastern Rhodopes (the Smolyan and Kardzhali Province) are strongly religious and have preserved the Muslim name system, customs and clothing, the Smolyan Province, which is largely populated by Bulgarian Muslims (approximately 117,000 or 71% of the population according to the Ministry of Interior in 1989). According to the 2001 census, 43 municipalities out of 262 have a Muslim majority. There were five municipalities with a Muslim population over 90 percent: Chernoochene (96.8 percent) has the highest share of Muslims, followed by Venets (95.9 percent), Satovcha (91.3 percent), Ruen (90.9 percent) and Kaolinovo (90.0 percent)(122,806 or 87.7%) and that only 58,758 people or 41.9% of the population of the province declared to profess Islam in 2001.
