Historical Background of Russia and Ukraine

To understand the Russo-Ukrainian War, we must first understand the historical relationship between the two countries.

Shared Origins

Both Russia and Ukraine trace their origins to Kyivan Rus, a medieval state that existed between the 9th and 13th centuries.

This historical connection is often referenced in political narratives.

However, over centuries, Ukraine developed its own national identity, language, and political aspirations.

---

Soviet Era (1922–1991)

Ukraine became part of the Soviet Union in 1922.

During this period:

• Ukraine experienced forced collectivization

• Millions died in the Holodomor famine (1932–1933)

• Ukrainian political independence was suppressed

Despite Soviet control, Ukrainian national identity persisted.

---

Ukraine Independence (1991)

When the Soviet Union collapsed in 1991, Ukraine became an independent country.

Important developments followed:

• Ukraine inherited nuclear weapons but gave them up in 1994

• Russia guaranteed Ukraine’s sovereignty under the Budapest Memorandum

• Ukraine gradually moved toward Europe politically and economically

This shift became one of the underlying tensions leading to the conflict.

Key Causes of the Russo-Ukrainian War

The Russo-Ukrainian War is driven by several interconnected causes.

1. NATO Expansion

Russia has long opposed NATO expanding eastward.

Countries that joined NATO after the Cold War include:

• Poland

• Estonia

• Latvia

• Lithuania

• Romania

Ukraine’s potential NATO membership was seen by Russia as a security threat.

---

2. Ukraine’s Western Alignment

Ukraine increasingly sought closer ties with:

• The European Union

• NATO

• Western economic institutions

Russia viewed this shift as a loss of influence in its traditional sphere.

---

3. The 2014 Ukrainian Revolution

In 2014, Ukraine experienced a major political uprising known as the Euromaidan Revolution.

The pro-Russian president was removed from power after protests against his decision to reject an EU agreement.

Russia viewed this as a Western-backed coup.

---

4. Annexation of Crimea

In March 2014, Russia annexed Crimea, a peninsula previously controlled by Ukraine.

This was widely condemned internationally and triggered sanctions against Russia.

---

5. War in Donbas

Shortly after Crimea’s annexation:

• Russian-backed separatists declared independence in eastern Ukraine

• Fighting began in the Donetsk and Luhansk regions

This conflict continued for years before the 2022 invasion.
