I have a dataset that says that Saxe Altenburg was part of some other entity (simply coded "263") until 1827.
I have been trying to figure out what the entity "263" is, but have not been able to do so.
I am thus posting this question here in the hopes that some history buff here might know more about what may have happened to Saxe Altenburg circa 1827.
Some details about the dataset:
It is oldish (metadata says 2003) and seems to be connected to the Correlates of War (COW) Project.
I can't find any accompanying documentation.
I have emailed lots of folks at COW but so far have gotten absolutely nothing. I have also emailed who I think might be the author (the metadata says the Author is one "dbennett" and I guessed that this was D. Scott Bennett at PSU), but haven't gotten a reply.
