In the Russian capital, thousands of people led by Moscow Mayor Sergey Sobyanin marched across the Red Square to commemorate the May Day.
The day, dedicated to workers around the world, is a public holiday in many countries.
It commemorates the struggle of the working class to win fair employment standards, historian Tatyana Sidorova told Anadolu Agency in Moscow on Tuesday.
People who worked most, earned less and did not have time to study and to top up their qualification, she added.
"These unjust conditions resulted in appearance of labor unions and labor movements which met a great resistance from the side of the industrial elite. But when the labor movement became mass, employers were forced to meet the demands and to improve work conditions," she said.
In Austria, over 100,000 people gathered in front of the Municipality of Vienna building, where far-right groups protested.

In Manila, a crowd of around 20,000 individuals from different labor groups -- the biggest number of protesters recorded since Philippines President Rodrigo Duterte assumed presidency in 2016 -- gathered on Tuesday and protested against labor contract executive order.
Earlier Tuesday, Duterte had signed an executive order aimed at ending illegal contracts and providing security to Filipino workers; however, protesters claimed it was "anti-workers" and useless.
