On 21 November 1990, CSCE participating States (today’s OSCE) signed the Charter of Paris for a New Europe, politically marking the end of the Cold War in Europe and setting out principles for a new era.

What happened
- The Charter reaffirmed commitments to democracy, human rights, rule of law, and the peaceful settlement of disputes.
- It framed European security as cooperative and rules‑based after decades of bloc confrontation.
- It became a foundational reference for the idea of a shared European security order.

Why it matters
- It is a key benchmark for assessing later gaps between declared principles and political practice.
- It helps explain why later deterioration is often described as a breakdown of a political compact, not a single event.

Key point
The Charter is the high point of post‑1989 optimism: an order built on consensus. Its erosion shows what happens when norms and trust lack credible enforcement.
