Konstantinos Karamanlis was the Third President of the Greek Republic. He succeeded Spyros Markezinis as the leader of the Greek Rally Party and won the elections of 1967.
During his Presidency, Greece was criticized by France and the UK because since 1951 the only party to come to power was the Greek Rally Party. However, the elections were never criticized by any state or NGO, as they were free and fair.
During his first term, he developed the Industry in Macedonia and expanded even more the Greek Army, which by now had more than 450,000 soldiers and was one of the most advanced armies of the world, equal to that of Israel and the UK.
In his second term, Karamanlis allowed the USA to establish military bases in Macedonia. He also helped the USA in the Vietnam War, sending more than 23,000 troops to fight in Vietnam. Greece also signed a military alliance with Turkey and Israel. Also Greece became in 1974 the world's ten largest economy.
In 1975 he gave the leadership of the Greek Rally to Panagiotis Pipinelis. He died in 1998.
