Głogów and Żagań — the Silesian duchies on the Oder and Bóbr

Głogów, Żagań. Which empire held this ground in which years — and, the part that matters, which archive that means.

Whose archive this ground was

YearsWho held itWhose archive that means
1251–1331 Duchy of Głogów (Piast) no registers survive

Before registers. Konrad I received the northern Głogów territory in 1251, and the Duchy of Żagań was split off in 1273.
1331–1526 Bohemian fief — Głogów and Żagań Geneteka · Szukaj w Archiwach · FamilySearch

King John of Bohemia seized Głogów as a fief in 1331; in 1349 half went to the Duchy of Żagań and half into the Crown of Bohemia. Matthias Corvinus conquered Głogów in 1488, and it became an immediate dominion of the Bohemian Crown in 1506.
1526–1742 Habsburg Bohemian Crown Geneteka · Szukaj w Archiwach · FamilySearch

The duchy passed to the Habsburgs through Ferdinand I after Louis II died in 1526.
1742–1815 Prussia — conquered Silesia Geneteka · Szukaj w Archiwach · FamilySearch

Prussia took Głogów with most of Silesia in 1742-48; the Treaty of Aachen (1748) confirmed it.
1815–1945 Prussia — Province of Silesia Geneteka · Szukaj w Archiwach · FamilySearch

The duchy was dissolved into the Province of Silesia in 1815. From October 1874 Prussian parishes were joined by civil registrars, and from 1 January 1876 the rule held across Germany.
1945–2026 Poland Geneteka · Szukaj w Archiwach · FamilySearch

Prussian Silesia east of the Oder-Neisse line was granted to Poland after the Second World War (Potsdam Agreement).

The rings are approximate — deliberately. They exist to shade which filing system a place fell under, not to adjudicate a border. A place near a ring's edge should be checked against both neighbours.

The map takes a range, and a range that crosses one of the rows above is where records get lost: the family never moved, and the archive on the far side of the handover will tell you it holds nothing.

Ranked with the regional ones first — a collection for a province is usually a better lead than a national index, though the national index is often where a name is actually written down. A free account opens the images.
