I don't know what you say as "dominance" with a sweeping statement.
You have to be very specific and define "dominance" carefully.
12 century Europe saw the first Renaissance (rebirth). Then the rebirth picked up steam in 14fth century.
During all this time, only Ottomans were somewhat comparable, but then they quickly fell behind in science and arts and industry.
During all this time, We the Muslims of India remained pretty much stuck within sub-continent.
During all this time, the birth place of Islam remained the heart of intellectual darkness.
So I'd hardly call it "dominance".
Many desi Muslims tend to take credit from Turkish or Berbers. But that's not fair.
Unless Muslims from sub-continent really went over and did an active participation in Ottoman or Berber governments, one should not even use the term "all Muslims" were dominant.
This is like an African from Congo taking credit of Moon landing, or an Ethiopian resident Jew taking credit for the theory of relativity.
Hope you get the point.

Did I say that I take credit for anything?
These terms like "West" or "Islamic World" are stupid as fcuk..but they are created by West themselves!!! Since I don't go into detail, I just write generic stuff...
"Islamic World" (if you take it as one) remained global superpower/global dominant force from 7th to 18th century...First it were Ummayads, Abbasids, Ottomans in Euro-Asia came, meanwhile Islamic Mughal Empire of india were economically probably the wealthiest in the world...meanwhile strongest regional powers like Timurid Empire was also "Muslims" ...Though there were blow-backs like fall of Spain, Mongol invasions etc..but "over-all" Islamdom enjoyed global supremacy for ~1100 years...
Similarly, from last 250 years or so..""West" (if you take it as one) is enjoying global supremacy..Whether it was British or French..whether German Nazi military machine or U.S...over-all, West is on top for past 2, 2.5 centuries...Now, West had its setbacks like WW2, civil war, Franco-German-British competition blah blah...
Remember, "West" isn't any 'civilization' just like "Islamic Civilization" isn't any one civilization..but if Westerners take "West" as one civilization..and "Islamic World" as one civilization too..then what can I do?
By the way, Europe didn't pick up steam until 16th century or so...and even then..Ottoman Empire remained the single most dominant empire on Earth till about mid-18th century....
Over-all, say in 17th century, "Islamic World" dwarfed West in terms of economic might, military power, trade, control of trade routes in Mediterranean sea, red sea, Persian Gulf, Industrial production etc etc...though at that time, West was "growing" faster, way faster than Islamdom..but didn't replace it yet. Kinda like today, China is growing MUCH faster than U.S/West in all fields..but it hasn't replaced them as number one yet!
But again, it is not me who started using terms like "West" vs "Islamic World" etc..It were Western retarded authors themselves....
