Looking for suggestions

I'm starting to run low on TBR books for the challenge; there's only one on my shelf (and that's a GR, when I've already met my goal for G), and two definites (as well as a few tentatives) on my wishlist. The categories where I need the most -- largely because of my tiered goal structure -- are D and P, so that's where I'm looking for help. Since I can't just search the group catalog by LC number, I'll ask for suggestions:

DB: History of Austria
DC: History of France
DD: History of Germany
DE: History of Greco-Roman World
DF: History of Greece
DG: History of Italy, Malta
DH: History of Low Countries
DJ: History of Netherlands
DJK: History of Eastern Europe
DK: History of Russia, Poland
DL: History of Northern Europe
DQ: History of Switzerland
DR: History of Balkan Peninsula
DX: History of Gypsies

or for

PB: Modern languages, Celtic languages
PC: Romantic languages
PD: Germanic languages
PF: West Germanic languages
PH: Uralic languages
PK: Indo-Iranian philology and literature
PL: Languages of Eastern Asia, Africa, Oceania
PM: Hyperborean, Indian, and artificial languages

Any recommendations?

Some guidelines:

No military history.

I don't like most biographies -- they spend too much time on people's personal lives, and less on what they actually did to become famous. Some memoirs, where the person isn't famous but has done interesting things, are good.

This is what I've read:

DB Holy Blood, Holy Grail
DF A Short History of Byzantium or The Secret History
DG Terry Jones' Barbarians - this may be dangerously close to military history, but I look at it as a history of the movement of early medieval peoples

Here are a few ideas, with comments. There's a lot more in my catalogue, but most of it pretty much unreadable for normal people. I took a look at your catalogue, lorax, and saw that you have some general books on history but not a lot in depth so I'm aiming for things that should be OK for an intelligent, educated person who doesn't read much history.

DC Roman Gaul and Germany (accessible but not lively)
DC Twelve Who Ruled (fascinating if you have any interest in revolutions or France)
DE The Mediterranean and the Mediterranean World in the Age of Philip II (OK, it's really long, but it's quite readable and a very influential classic)
DF The Making of Byzantium (not as long, should be reasonably readable)
DF Citadel to City-State (written for undergraduates in classics, so assumes some knowledge of ancient history but otherwise explains things fairly well)
DG Villa to Village (short and readable, but may require some prior knowledge of medieval history or archaeology)
DG The Roman Empire Divided (written for nonspecialists)
DG Before the Normans (easier if you know a bit about Italy already)
DH The Dutch Revolt (it's about a war of independence, so it may fall under the ban on military history, but it gives a comprehensive political and social view, not just a narrowly military view of it)
DL Towns in the Viking Age (written for undergraduates, but British ones)
