The Revival of Internal Colonialism as a Scholarly Model?

Between about 1980 and 2009 or so it seemed that the concept of internal colonialism completely disappeared from contemporary scholarship. However, in recent years I have seen an increasing revival of the concept. I am not sure what to make of this. I personally think the concept is a lot more useful than most social science models. But, for what ever reason it wasn't very popular in the 1980s, 1990s, or the first decade of the 21st century. Its recent revival also seems puzzling since there doesn't seem to be any single origin or inspiration for the new crop of scholarship making use of the model. If anybody has any insights into the reasons behind this new interest in a model that had seemingly died in the 1980s please leave comment below. My own contribution to the use of internal colonialism as a model for understanding the relationship between marginalized ethnic groups and their surrounding society and ruling government is here.
