The Eastern Mediterranean has become one of the world's hottest conflict zones with longstanding historical claims. The Mediterranean Sea importance comes from its strategic position for international trade communication. With many states having direct access to the Mediterranean Sea, peace is essential for the area's future prosperity. August 2020 witnessed an escalation between the Eastern European nations of Turkey, Greece, and Cyprus over natural gas exploration in the Mediterranean Sea. Previous research has shown that most maritime conflicts are resolved via negotiation, litigation, or arbitration. However, this is not the case with the Mediterranean Sea disputes. While most maritime territorial disputes remain dormant and rise to the surface only when states compete for resources, this dispute has no exception. The August 2020 crisis is an on going crisis which surfaced a decade ago when the United States Geological Survey (USGS) discovered a massive amount of natural gas deposits in the Mediterranean Sea. Although discovering mineral resources could take the region into a new era of cooperation, it was otherwise as competition fired by old antagonism started to appear between the Mediterranean countries on one side and Turkey on the other side. This research analyzed the Turkish role in August 2020 using the Realism theory via a qualitative research methodology. Data were collected using documents and interviews. The significance of this research lies in providing a new understanding of the crisis by studying the changes in regional powers and domestic power components (Political and economic) and reflecting their influence on the Turkish Foreign Policy. The research shows that the crisis arose due to the emergence of Turkey as a regional power accompanied with a decline in other powers such as the USA, in addition to the deterioration of relations between Turkey with Greece, Cyprus, Egypt, and Israel, which pushed these states towards collaboration to isolate Turkey. That collaboration was represented in the Eastern Mediterranean Gas Forum that excluded Turkey's membership and trilateral partnerships between these states. In addition, with the growing perception of isolation following the EastMed gas pipeline project that undermined the Turkish plans to become an energy hub. Due to and the domestic power components (political and economic) within Turkey, the Turkish leadership's had a perception that Turkey's interests - being the biggest economy, largest regional navy, owner of the longest coasts- must always be considered in any future projects in the area. Therefore, the study showed that the crisis soared due to the assertive Turkish efforts to protect its maritime claims against Greece, Cyprus, Egypt, and Israel.
