In a telephone conversation with President Erdogan Friday evening, President Buhari expressed the hope that the results of the recently held elections will strengthen democracy and lead Turkey towards more economic prosperity.
Maduro, who tweeted the praise as a video message, was among more than 50 high-level foreign leaders, including 22 heads of states, who attended Erdoğan's inauguration ceremony at the presidential complex in Ankara on July 9.
Erdogan narrowly won a referendum a year ago to replace his country's parliamentary democracy with a system featuring an all-powerful presidency, and followed that with a hard-fought election victory last month to the newly strengthened post.
Erdogan will face immediate and major challenges in his second term, posed by an imbalanced fast-growing economy and foreign policy tensions between the West and Turkey, a North Atlantic Treaty Organisation member.
Erdogan, 64, says a powerful executive presidency is vital to drive economic growth, ensure security after a failed 2016 military coup and safeguard Turkey from war across its southern border in Syria and Iraq.
On the eve of Monday's inauguration authorities dismissed more than 18,000 state employees - majority from the police and army - in what the government said would be the final decree under emergency rule imposed following a failed 2016 coup.More news: Chris Froome barged off road during Stage 1 - Tour de
He will then head to more challenging encounters at a North Atlantic Treaty Organisation summit in Brussels where he will meet with U.S. counterpart Donald Trump.
The president will sit at the top of a vertical power structure marked by a slimmed-down government with 16 ministries instead of 26 and multiple bodies reporting to him.
"As president, I swear upon my honor and integrity, before the great Turkish nation and history, to work with all my power to protect and exalt the glory and honor of the Republic of Turkey", Erdogan said in his speech to Parliament after being sworn in.
In one of the most significant changes, the European Union affairs ministry, set up in 2011 to oversee Turkey's faltering bid to join the bloc, will be subsumed into the foreign ministry.
Prime Minister Binali Yildirim now goes down in history as the 27th and final holder of the post in Turkey.
"Turkey is entering a new era with the presidential oath ceremony on Monday", Erdogan told his ruling AK Party at the weekend.More news: Johnny Depp Sued For Allegedly Assaulting City Of Lies Crew Member
Erdogan named his son-in-law Berat Albayrak as treasury and finance minister in an updated cabinet that excluded former deputy prime minister Mehmet Simsek, seen as the main market-friendly minister in the previous government.
The most intense attention will focus on who will be responsible for foreign policy and the economy.
Current Foreign Minister Mevlut Cavusoglu could, in theory, continue in his job but reports have said Erdogan may choose his spokesman, Ibrahim Kalin, or even spy chief Hakan Fidan to succeed him.
He won last month's election with 52.6 per cent of the vote, ushered in the executive presidency that ends parliamentary governance and boosts the powers of the formerly ceremonial presidency.More news: Turkey's Erdogan appoints son-in-law as finance minister
