Most group members say Maduro should quit in favor of opposition leader Juan Guaido - who declared himself interim president last month - and are calling for a new presidential election in the troubled OPEC nation.
The coordinated recognition by a flood of European Union nations including Britain, Germany, France and Spain followed the expiration of an ultimatum for Maduro to call a new presidential election, aligning them with Washington and against Russian Federation and China.
The countries urged Guaido, 35, who leads the National Assembly, to hold free and fair elections as soon as possible. However, according to diplomatic sources in Brussels, Italy has blocked an EU-wide statement of the bloc's support for Guaido due to conflicting interests within the Italian coalition government.
"We are working for the return of full democracy in Venezuela: human rights, elections, and no more political prisoners", Spanish Prime Minister Pedro Sanchez said in a televised announcement.
Meanwhile Guaido, already recognized by the US, Canada, Australia and several Latin American countries, said he would soon lobby the European Union for badly-needed humanitarian and economic aid.
Asked in Brussels on Monday whether Ireland would follow other major European Union nations in recognising him, Ireland's Foreign Minister Simon Coveney told reporters: "No, our position has been clear".
"We are not beggars", Maduro said in a speech to troops broadcast on Venezuelan state TV.
Since then, he has been courting the worldwide community - including Maduro's staunchest supporters, Russian Federation and China - as well as Venezuela's military leaders.
President Maduro has rejected offers of aid from the United States, having told his supporters on Saturday that Venezuela was not "a country of beggars".
"I swear ... that I will defend with my life this fatherland under threat", Maduro said at an event in Aragua state in the north, commemorating the 27th anniversary of a failed coup by his late predecessor Hugo Chavez.

The fans were just wonderful . "I've never seen or heard anything like it and I will remember it for the rest of my life really". Cushions believed to be from the plane were found on a beach near Surtainville, on France's Cotentin Peninsula, on Monday.
President Maduro also had choice words for Washington's transatlantic allies, describing Europe's ultimatum to hold new elections as "the stuff of empires, of colonial times".
Trump said us military intervention was under consideration in an interview with CBS aired on Sunday.
"The people of Venezuela have suffered enough".
"The 5-Star Movement and this government will never recognize people who appoint themselves president".
USA leader Donald Trump will be responsible for a bloodbath that would mirror the war in Vietnam if he gets militarily involved in Venezuela, President Nicolas Maduro has warned, describing the potential conflict as a "David against Goliath" scenario.
Some of the EU countries backing Guaido are part of a newly formed "International Contact Group" of eight European and four Latin American nations.
Maduro claims the U.S. pledge to deliver $20 million in aid relief precedes a military intervention.
He added that "no one imposes an ultimatum on Venezuela".
Maduro, for his part, stood defiant, accusing the United States of preparing a coup in the South American country and rejecting a US -backed effort to send emergency food and medicine into his country.
If all European countries follow in the footsteps of the Trump Administration, their decision to recognise Guaido could potentially cut the Venezuelan Government off from any accounts or assets in those countries.
