Italy like means : weak native states with frequent foreign invasion and influence, with common language and culture ?
for Iberia
- southern Iberia during Almoravid and Almohad is controlled by foreign power.
- Taifa and Asturias is native states
- while Barcelona, Portugal and Navarre is influenced by French and English
if they continued to be divided instead marrying each other Italy-like Iberia is large possibility.
for Balkans, they are Italy like for long time
- Greece controlled by Ottoman
- Hungary is influenced heavily by Germans (especially Austria)
- Wallachia, Moldavia and ragusa as independent native states
- Hungary and Albania also sometime become strong native states.
less complete Ottoman conquest might make non-Ottoman influence (Russia, venice, poland and Austria) stronger. Unlike Italy, Balkans didn't have common language however, so strong nationalism later is near impossible.
Annatolia
this one difficult, Northeast could be Georgia controlled, Northwest could be Greece/Constantinople controlled, south could be Arabs/Antioch influenced. but Anatolia plateau and fertile areas in Northwest will give anyone who control it strong advantage to unify the entire pennisula. And Anatolia based states is often strong enough to conquer others (Hittite, Byzantine, Ottoman) so Italy-like is difficult to pull.
