Git throws error: refusing to merge unrelated histories, when git history is lost or got corrupted and you try to merge the pull. The solution to this problem is to use --allow-unrelated-histories flag.
Consider this code –
git pull origin master fatal: refusing to merge unrelated histories
This situation may have arise by losing git history in local repository. As a solution to this problem, you can simply use --allow-unrelated-histories flag –
git pull origin branchname --allow-unrelated-histories
