herm consider archeology in the basque country (something like that where the central goverments prefer to ignore a few parts since there´s nationalist movements who could use the information gathered to distort the findings ?)

but even then the politics go into the historians who are suposed to interpret the evidences and findings and not the archeological work per se

ofc i have only worked in a few dig sites as a volunteer (i worked with a teacher who as cracked the writtings of the southern iberians when i was in the algarve) and the chaminé mound/mount in my land where there´s a few roman ruins but as i said i´m not that deep into it i know that normally dig teams are hard to get and the funding ain´t much so it´s mostly volunteer work at least in portugal
