The first settlements in Regensburg date to the Stone Ages. The Celtic name Radasbona was the oldest name given to a settlement near the present city. Around AD 90 the Romans built a small "cohort-fort" in what would now be the suburbs. From 1663 to 1806, it was the permanent seat of the Reichstag (Imperial Diet) of the Holy Roman Empire. In 1809 the city was partially destroyed by the French under Napoleon. A year later Napoleon formed the Kingdom of Bavaria, with Regensburg becoming a part of it.

The Reichstag (Heiliges R�misches Reich)  was the legislative body of the Holy Roman Empire. It was divided into
(a) The Council of Electors, which included the Electors of the Holy Roman Empire.
(b) The Council of Princes, which included both laypersons and clerics.
(c) The Secular Bench: Princes (those with the title of Prince, Grand Duke, Duke, Count Palatine, Margrave, or Landgrave) each held individual votes; some held more than one vote on the basis of ruling several territories.
Also, the Council included
(d) Counts or Grafs, who were grouped into four Colleges: Wetterau, Swabia, Franconia, and Westphalia. Each College could cast one vote.
(e) The Ecclesiastical Bench: Bishops, certain Abbots, and the two Grand Masters of the Teutonic Order and the Order of St John each of whom had individual votes.
 (f) Certain other Abbots who were grouped into two Colleges: Swabia and the Rhine. Each College had one vote.
(g) The Council of Imperial Cities, which included representatives from Imperial Cities grouped into two Colleges: Swabia and the Rhine. Each College had one collective vote. .

The Empire (German: Heiliges R�misches Reich) (Italian: Sacro Romano Impero) was formally dissolved on August 6, 1806 when the last Holy Roman Emperor Francis II (from 1804, Emperor Francis I of Austria) resigned.
