1 week ago - The doctrine rejects the United ... of the Sea (UNCLOS; which Turkey has not ratified) and advocates for control over roughly 462,000 km2 (178,380 mi2) of maritime territory. First promoted in 2006, it was politicized after the July 2016 failed coup attempt as part of the Republic of Turkey's pursuit of strategic autonomy. Since 2019, Blue Homeland has ...

June 24, 2025 - In line with its pursuit of regional power and an autonomous foreign policy, Ankara envisioned a robust maritime presence to defend its interests in surrounding seas, including the Black Sea and the Mediterranean. Dubbed the “Blue Homeland” doctrine, it aimed to enhance Turkey’s presence in its sea areas and project power where it has a military presence, such as Somalia and Libya.

July 11, 2024 - Also in line with the terms of the convention, Turkey has had a long record of resisting any extended stay by non-riparian, including NATO, warships in the Black Sea. This policy, shaped by concerns of preventing regional crises from escalating and maintaining a fragile balance with Russia, has caused Turkey’s loyalty to be perceived “at best, as ambiguous and, at worst, suspicious” by some of its NATO allies, especially the United States.

In the Black Sea, Turkey’s balancing act between its NATO commitments and its desire to maintain stable relations with Russia has been one of the defining features of its regional strategy. The Eastern Mediterranean is likely to hold greater strategic significance for Tur­key compared to the Black Sea. It is no coin­cidence that the Blue Homeland doctrine has emerged and been promoted in the offi­cial discourse in the Eastern Mediterranean context.

March 14, 2022 - The main goal of the Blue Homeland doctrine is to achieve and consolidate Turkey’s control in its surrounding seas to raise its regional and international influence and eventually to control new energy resources. In adhering to the Blue Homeland, Turkey implements an expansionist energy policy in the Eastern Mediterranean, exploring for gas reserves.

November 25, 2025 - As a definition, it encompasses all Turkey’s declared or undeclared maritime jurisdiction areas (internal waters, territorial waters, continental shelf, Exclusive Economic Zone), as well as rivers and lakes.

September 19, 2022 - This is culminating in Turkey’s ‘Blue Homeland’ ambitions – the idea that Turkey should reclaim mercantile and maritime power in the Mediterranean. Using this toolbox and clearly being informed by lessons learned in Syria, Turkey is adopting an increasingly aggressive and revisionist foreign policy posture.

July 27, 2023 - Although outside observers initially saw “Blue Homeland” as the expression of Turkish claims to energy reserves in the Eastern Mediterranean, the vision is transcontinental, if not global. Exploitation of natural resources is only one aspect of the plan, the ultimate goal of which is to control the eastern sea transit routes to Europe. The historical foundation of the doctrine is the position that, for Turkey to regain its deserved status, it must acquire sea power.

July 4, 2021 - Turkey’s expansionist energy policy in the Eastern Mediterranean is underpinned by a maritime doctrine that has raised the spectre of naval confrontation with Nato allies Greece and France.

Turkish President Recep Tayyip Erdoğan has remained steadfast in spite of threats of sanctions and increased diplomatic isolation. “While performing our duties, we are proud to wave our glorious Turkish banner in all our seas,” one officer declared before Erdogan in October 2019. “I submit that we are ready to protect every swath of our 462 thousand square meter blue homeland with great determination and undertake every possible duty that may come.”

For the purpose of enhancing peace and stability in the Black Sea area, by increasing regional co-operation, and improving good relationship, the idea of establishing a multinational naval on-call peace task force “The Black Sea Naval Co-Operation Task Group-BLACKSEAFOR” has been initiated ...

The strategic position of the Black Sea and Turkey as the country controlling access to the Black Sea might make Western countries more willing to see past Erdogan’s behavior and attempt to improve the relations between the bloc and Turkey. However, it is important to keep in mind the opinion of Turkish people that do not necessarily consider the EU as the most attractive and reliable ally. Domestic narratives and policymaking play an important role in EU-Turkish relations, and Erdogan’s attempts at centralizing power and unifying Turkey by creating a stronger religious and nationalist narrative have alienated it from European leaders.
