The Umayyads, specifically the first Umayyad ruler, Mu'awiya I.
The first Islam State Capital was Medina, then Damascus, then Baghdad. Never Mecca was an Islamic state capital although Mecca is the most sacred Islamic city.
It depends what you call "Muslim territory" since there are Muslims all over the earth, but Djakarta, the capital of Indonesia, is in a predominantly Muslim country and is about as far from Mecca as you can get.
Mecca (or Makkah) was never a capital of any Islamic caliphate or an Islamic country. Medina (or AlMadinah) was the capital of the Islamic Caliphate until 'Ali shifted it to Kufa, Iraq and his rival Mu'awiya shifted it to Damascus, Syria then the Abbasid shifted it to Baghdad. Today, Mecca is a holy city in Saudi Arabia, but never a national capital.

There is no 'Muslim capital' because Muslims live in different countries with their differing capitals all around the world. However, the 'point of adoration', the Qibla is Mecca where the Kaaba is.
Mecca has been the center of the Muslim culture since 610 CE, when Muhammad the Islam prophet was said to have started receiving visions from God.
"Golden Age" is undefined. I would consider the golden age of the Muslim Civ to be the Abbasids c. AD 800. If that's true the answer is Baghdad. The center of the Muslim Civ originally was Mecca (630-661) and then Damascus (661-750).
While Muhammad was alive, the first capital of the Islamic Nation was declared in Medina, Saudi Arabia in 622 C.E. with the Constitution of Medina. Once Muhammad conquered Mecca, Saudi Arabia in 630 C.E., the capital was transferred to Mecca.
For Muslim rulers in pre-colonial Africa, the hajj (pilgrimage to Mecca) was a way of establishing relationships with other rulers. Mansa Musa's pilgrimage made his kingdom famous for its wealth in gold.
