comment Histidine aromaticity
I was referring to the basicity of the side chain itself. Why is its pKa neutral?

Rather, the protonation of imidazole generates a cation where the positive charge is delocalized, which contributes to its stability. I still do not see why it is a weak base.

But the protonation occurs on the pyridine-like nitrogen. It is in sp2 configuration and its lone pair is not involved in the aromatic pi system.
