2.2.4 2.a; 2.2.4 3.a - Challenges to Ukraine’s sovereignty

Ukraine, recognised borders and contested control

Ukraine is an Eastern European state with Kyiv as its capital and access to the Black Sea; it became independent following the dissolution of the Soviet Union in 1991.

In 2014, Russia occupied and purported to annex Crimea, while armed conflict developed in eastern Ukraine. UN General Assembly Resolution 68/262 reaffirmed Ukraine's territorial integrity and stated that the March 2014 referendum in Crimea could not provide a basis for changing its status. The case therefore requires a distinction between a claim and its international recognition. UN record, 27 March 2014.

Russia began its full-scale invasion on 24 February 2022. In March 2022 the General Assembly deplored the aggression as a violation of the UN Charter and demanded withdrawal. Further Russian claims to annex Ukrainian regions in 2022 did not turn military occupation into a generally recognised lawful boundary change. The Assembly's February 2025 resolutions again reaffirmed Ukraine's sovereignty and territorial integrity within internationally recognised borders. UN record, 2 March 2022 and 24 February 2025.

Maps must consequently specify their variable. International borders, areas under Russian occupation, areas claimed by Russia and a dated front line are different layers. A historical map of control represents its stated date. A shift in control can change residents' access to institutions and movement immediately while leaving the international legal status of the territory unchanged.

Causes and challenges to the government

The challenge involves unequal interstate power, competing geopolitical projects and attempts to determine Ukraine's political and territorial future.

Ukraine's government seeks to exercise authority over its recognised territory and choose its external relationships. Russia's intervention seeks to constrain that authority and has advanced security and historical claims to justify its actions. Such claims are part of the geopolitical evidence to analyse, not a reason to present the use of force as legally established or inevitable. The UN's condemnation distinguishes the international institutional assessment from the invading state's account.

Political and social geography matters, but identities cannot be read as automatic territorial preferences. Language, family connections and historical experience vary within Ukraine; they do not establish that every Russian-speaking person supports Russian rule or that military intervention follows necessarily from diversity. A government must maintain legitimacy and services for a varied population while responding to an external attack.

Economic capacity shapes that response. Mobilising defence, supporting displaced people and repairing infrastructure compete for finance and personnel. External financial and military support can strengthen the state's capacity while creating dependence on partners' decisions. Infrastructure attacks can reduce electricity for households, industry and public services. The IEA's September 2024 assessment documents repeated attacks on generation and transmission assets, showing how control over an essential system affects the ability to govern as well as the economy. IEA, Ukraine's energy system under attack.

The challenge is therefore not only defending a line on a map. It includes sustaining tax revenue, services, public trust and international support while governing under conditions of danger and uncertainty. These mechanisms explain why formal sovereignty and effective capacity can diverge.

Worked explanation — challenges to effective sovereignty

Explain how economic and political factors can challenge the sovereignty of a state you have studied. Russia's full-scale invasion of Ukraine on 24 February 2022 directly challenged the Ukrainian government's ability to govern its recognised territory. The UN General Assembly's March 2022 demand for withdrawal reaffirmed a distinction between legal sovereignty and the control exercised through military force. Occupation can prevent national institutions from administering a locality even while international recognition of Ukraine's territory continues.

Economic systems extend this challenge beyond the front line. The IEA's September 2024 assessment describes repeated attacks on electricity generation and transmission. Electricity supports hospitals, communications, water supply and production, so disruption weakens the government's practical ability to maintain services and revenue. Repairs compete with defence and assistance for displaced people, increasing the importance of external finance and equipment. Partners' decisions then affect how quickly Ukraine can restore capacity. Political authority, infrastructure and economic resources therefore interact: a government can remain recognised and administer a city while its effective capacity is constrained by attacks on the networks serving it. The explanation develops mechanisms within the named case rather than treating recognition as a complete measure of power.
