Battle of Levounion 1091 not copyright violation and (Manzikert- Anatolia was not ethnic cleansing) 

Pechenegs had been driven out of their homeland by the Cumans and settled in Northern Bulgaria since some years, they raided and invaded Byzantine Thrace with their families and intended to settle at the Maritza river,[1]

But at the Battle of Levounion 1091 the Pechenegs were attacked by a combined army of Byzantines with Cuman mercenaries, the Pechenegs were almost totally killed, soldiers and civilians, this battled nearly annihilated the Pecheneg people. Later the survivors were massacred in the Battle of Beroia. (This is clearly ethnic cleansing, even if they were a newly migrated people to the Balkans.) 

I added:
At the Battle of Levounion (1091), the Pecheneg, a nomadic Turkic people from the Pontic-Caspian steppe, were nearly wiped out by the sedentary Byzantine Greeks and nomadic Cumans.{{cite book|last=Agbedo|first=Chris|title=Problems of multilingual nations  the Nigerian perspective|year=2007|publisher=Fidgina Global Books|location=Enugu, Nigeria|isbn=9789788132844|page=89|url=http://www.google.com/search?tbm=bks&hl;=nl&q;=ethnic+cleansing+greeks+pechenegs&btnG;=#hl=nl&tbm;=bks&sclient;=psy-ab&q;=The+Pechenegs%2C+nomadic+Turkic+peop-o+from+the+steppe%2C+were+nearly+annihilated+at+the+Battle+of+Levounion+by+a+combined+Byzantine+and+Cuman+army+in+1091.&oq;=The+Pechenegs%2C+nomadic+Turkic+peop-o+from+the+steppe%2C+were+nearly+annihilated+at+the+Battle+of+Levounion+by+a+combined+Byzantine+and+Cuman+army+in+1091.&gs;_l=serp.12...21850.21850.3.22808.1.1.0.0.0.0.0.0..0.0...0.1...1c..15.psy-ab.NHxON2jEZfU&pbx;=1&bav;=on.2,or.r_qf.&bvm;=bv.47244034,d.d2k&fp;=1f7c60039cb2be7d&biw;=1438&bih;=647

Original sentence was: The Pechenegs, nomadic Turkic people from the steppe, were nearly annihilated at the Battle of Levounion by a combined Byzantine and Cuman army in 1091.

I changed this into  At the Battle of Levounion (1091), the Pecheneg, a nomadic Turkic people from the Pontic-Caspian steppe, were nearly wiped out by the sedentary Byzantine Greeks and nomadic Cumans.

Manzikert Anatolia
This was added from the same book: After the Battle of Manzikert (1071), Greek populations of Anatolia were ethnically cleansed by nomadic Seljuk Turks

But the original sentence in the book was:[1]
The ethnic cleansing of sedentary Greek population of Anatolia by nomadic Seljuk Turks after the Battle of Manzikert in 1071.

If Levounion is copyright violation than this is also.

The idea that Seljuk Turks ethnically cleansed Anatolia is not true, Anatolian Greek populations survived till 1922, the Population exchange between Greece and Turkey.

Claiming Seljuks ethnically cleansed Anatolia is historically incorrect, it had a multicultural population, besides Seljuks had a sedentary state Seljuk Empire,  besides this claim was based upon one source, which was added by cherry picking and snippet abuse. So this must be removed  because of factual inaccuracy.
