A NATO member of about 86 million straddling Europe and Asia, led by Recep Tayyip Erdoğan and balancing the West, Russia and the Middle East.
See it on the Geopolitics map →The picture
About 86 million people; GDP about $1.4 trillion. A presidential republic since 2018, with power concentrated in Erdoğan; his main rival, Istanbul mayor Ekrem İmamoğlu, was jailed in 2025. Strengths: NATO's second-largest army, a booming drone industry, control of the Turkish Straits, factories tied to the EU customs union. Weaknesses: inflation that peaked near 85% in 2022 and was still about 30% in 2025, plus democratic backsliding. Investing: iShares MSCI Turkey (TUR) and similar ETFs, heavy in banks; lira risk is high.
Why it matters
Its grip on the Bosporus, its army and its ties to both Kyiv and Moscow make it a swing power in the Black Sea, Syria and the Caucasus.
Key facts and numbers
TurkStat and IMF data, NATO force figures, court records in the İmamoğlu case and the Montreux Convention text. Independent economists dispute official inflation figures. As of 2026.
What to watch
Outlook: whether disinflation holds, and whether Erdoğan, barred from another term unless parliament calls an early election, finds a way to run again in 2028.

▸Turkey (Türkiye) backs Azerbaijan in Armenia–Azerbaijan conflict and 2025 peace dealFact
The relationship
Turkey, which calls Azerbaijan 'one nation, two states', supplied Bayraktar drones and advisers that helped Azerbaijan win the 2020 war and retake Nagorno-Karabakh in 2023. It now backs the 2025 deal's planned transit route across Armenia, which would link Turkey to Azerbaijan and Central Asia.
Since when and why
The 2020 war (September–November); the 2021 Shusha Declaration alliance; the September 2023 offensive; the August 8, 2025 White House deal agreeing the planned 'Trump Route' corridor.
How we know
The Shusha Declaration text, Azerbaijani combat footage of Turkish drones, and official statements from Ankara, Baku and Yerevan.
What to watch
Disputed: reports that Turkey moved Syrian mercenaries to fight in 2020, which Ankara denies; and whether Turkey–Armenia border normalization will follow the peace deal.
▸Recep Tayyip Erdoğan leads Turkey (Türkiye)Fact
The relationship
Under the system adopted in 2017, Erdoğan is both head of state and head of government: he appoints ministers, senior judges and central-bank governors and rules by decree in many areas. He leads the AKP, which governs in alliance with the nationalist MHP.
Since when and why
Ankara; the executive presidency took effect in 2018. He was re-elected in a May 2023 runoff with about 52% of the vote.
How we know
Turkey's constitution as amended in 2017, Supreme Election Council results and presidential decrees.
What to watch
How Turkey's institutions would function after him, and whether court cases against the opposition CHP tilt the next election.
▸Turkey (Türkiye) is a member of NATOFact
The relationship
Turkey joined in 1952 and fields NATO's second-largest army, guarding the Black Sea straits and hosting the Incirlik air base. It is also a difficult ally: it bought Russian S-400 missiles, which got it removed from the F-35 program, and delayed Sweden's entry until 2024. It hosted the 2026 summit.
Since when and why
Joined February 1952 alongside Greece; S-400 delivery 2019; Ankara summit July 7–8, 2026, hosted by President Erdoğan.
How we know
NATO accession records, US sanctions on Turkey's defense procurement agency (December 2020), and the 2026 Ankara Declaration.
What to watch
Whether Turkey returns to the F-35 program, and how it balances NATO duties with ties to Russia; allies remain wary.
▸Turkey (Türkiye) controls Bosporus and the Turkish StraitsFact
The relationship
Istanbul straddles the Bosporus, making Turkey the gatekeeper of all Black Sea sea trade. The 1936 Montreux Convention restored its full control over the straits and lets it regulate warship passage. Ankara used that power in February 2022 to close the straits to warships of countries at war, then helped broker the Black Sea grain deal.
Since when and why
Signed at Montreux, Switzerland, on July 20, 1936; invoked by Turkey on February 28, 2022.
How we know
The convention's text, Turkish Foreign Ministry statements and naval tracking of transits since 2022.
What to watch
Whether Turkey keeps strict neutrality if Russia and NATO ever clash directly, and how a future Kanal Istanbul would square with Montreux.
▸Turkey (Türkiye) is the main backer of SyriaWidely agreed
The relationship
Turkey backed Syria's rebels from 2011, hosted up to 3.7 million refugees and shielded the last rebel enclave in Idlib, where Ahmed al-Sharaa's HTS ruled. After Assad fell in December 2024 it became the new government's main patron, offering military training, energy and reconstruction deals, and pressing it to absorb the Kurdish-led SDF.
Since when and why
Ankara, Damascus and northern Syria since 2011; post-Assad defense cooperation from 2025; Erdoğan welcomed the January 2026 Syria–SDF deal.
How solid?
Official visits and agreements between Erdoğan and al-Sharaa, Turkey's troop presence in northern Syria and UNHCR refugee data. Most analysts call Turkey the top backer; Gulf states also fund Damascus.
What to watch
Disputed: how much Turkey steered HTS's December 2024 offensive, and whether Turkish bases in Syria will clash with Israeli interests.
▸The Kurds and the PKK peace process saw the PKK end its war on Turkey (Türkiye)Fact
The relationship
The PKK waged an insurgency in Turkey from 1984 that cost about 40,000 lives. Answering a February 2025 call by jailed founder Abdullah Öcalan, it declared its dissolution in May 2025, burned weapons in July and pulled fighters back to Iraq. Turkey's parliament is now moving laws to reintegrate ex-fighters.
Since when and why
İmralı island prison, Ankara and northern Iraq; dissolution announced May 12, 2025; weapons ceremony near Sulaymaniyah, July 11, 2025; reintegration bill filed August 2026.
How we know
PKK statements, video of the weapons ceremony, Turkish government statements, and the February 2026 parliamentary commission report and resulting bill.
What to watch
Debated: whether a reintegration bill that excludes senior commanders can bring fighters home for good, and whether spoilers on either side could still derail the process.
