Actually yes, BiH:).

Beginning with 18th century onwards, Montenegrins or Serbs or call them what you want (it's irrelevant since modern concept of nation and ethnicity is later invention) migrated to parts of then Bosnian eyalet which were depopulated due to wars and epidemics which decimated local rural population.

Landholders of the time, bosnian muslims (Bosniaks in contemporary meaning), beys and agas introduced/invited/accepted families (or parts of clans basically) to settle their lands. Later on, especially with decline of ottoman rule and further instability (especially in border areas with Montenegro and hajduk/looter/robber activities) which led to further depopulation or domestic population (of all religious groups but muslims lost most of the number due to their military obligation and losses stemming from that and ofc don't forget epidemics - last plague epidemic in first decade of 19th century was quite deadly especially in urban places) and immigraton of landless, poor and groups of people that, due to harsh life in Montenegro, emigrated to nearest other areas/countries. I can write basically a novel length of comment to add and explain other factor and social and political circumstances that led to Montenegrin emigration to BiH and then another novel to start with events in 20th century.

Basically a lot of contemporary Serb population, especially in East Herzegovina and East Bosnia (a looot in Foca, Čajniče and further south towards Gacko and Bileća) can trace their roots to Montenegro.

This is NOT denying the fact that orthodox population of BiH (primarily parts of contemporary Serb declared population in East Herzegovina and East Bosnia) lives here for centuries and longer.

In the end, without any need to measure who's nation or ethnic group has "strongest" "claim" to areas that are todays BiH, Croatia, Serbia, Montenegro etc., just to add that all of us (exyu minus Slovenia and Macedonia Slavic peoples) are historically soo intermixed with each other, soo many migration cycles and routes.

Our contemporary national and ethnic self identification is another thing (which should be respected and respecftul)but it is not supposed to be a cause for conflict or some heated online debate.

Peace Živio!
