After only ten years of reconstruction he signed another success for his country: Poland joined the North Atlantic Treaty Organisation (NATO).
Sensitive to Chechen matters, Geremek proposed “Memorial”, the Russian most known organisation for the defense of human rights, as candidate for the Nobel Peace Prize.

In June 2001, he founded the centre party The Democratic Union (later merged into the The Freedom Union), led its European election campaign and, once elected MEP, missed the European Parliament presidency for only a few votes.

ELDR President Annemie Neyts-Uyttebroeck: “In 2004, Professor Geremek was nominated by the European Liberal Democrats to run for the Presidency of the European Parliament as he was one of the living symbols of Europe’s reunification. With his death Europe has lost a proponent of European solidarity, co-operation and freedom.”
In 2007 he refused, as an act of civil disobedience, to submit a new law-bound declaration that ordered everyone in a public position - including lawmakers, government ministers, judges, journalists and teachers - to sign declarations confirming they didn't co-operate with Communist era secret police, if they hadn't already done so. ELDR declared the new law as a risk to free journalism and free academic researches.
