Other artists voiced similar sentiments.

Bambie Thug, representing Ireland, screamed “love will triumph hate” as they finished their song, Doomsday Blue; while Portugal’s contestant, Iolanda, told the crowd: “Peace will prevail.”

Two former contestants, Alessandra Mele and Käärijä, pulled out of announcing their countries’ jury scores; Mele cited Israel’s participation as a factor, while Käärijä said “it doesn’t feel right” (to give out points).

However, there was a swell of support for Golan’s song, which came second in the public vote with a score of 323. The UK was one of 15 countries where the public gave the 20-year-old the maximum of 12 points.

Adding to the drama, Dutch contestant Joost Klein was disqualified from the contest on Saturday, after he was accused of making “unlawful threats” to a female member of the production crew.

The singer was reported to police after the incident occurred backstage on Thursday. Organisers subsequently decided to exclude him from the contest, saying they had a “zero-tolerance policy towards inappropriate behaviour”.

In a statement, Dutch broadcaster Avrotros called the decision “disproportionate” and said Klein had been filmed backstage when he had “repeatedly indicated” that he did not want to be.

Elsewhere, Eurovision was Eurovision.

Finnish artist Windows95Man performed a 1990s house banger with his trousers off, and Croatia’s Baby Lasagna sang about a country boy who sells his cow and moves to the big city.

Bambie Thug gave one of the night’s most memorable performances.

The self-described “goth gremlin goblin witch” appeared on stage in a circle of candles, summoning a demon then dancing ballet with it, before screaming at the top of their lungs.

A hit with viewers, it ultimately took sixth place, with 278 points.

That makes it Ireland’s best result in a quarter of a century.

The contest was held in Sweden, exactly 50 years after Abba gave the country its first Eurovision win in 1974.

Rumours flew around Malmö that they would appear to mark their golden anniversary – even though the band themselves denied it.

In the end, they only appeared in a short video, in the form of their “abbatars” from the virtual Abba Voyage concerts in London.

The quartet briefly reminisced about the success of their song Waterloo, which was then performed by three other Eurovision winners: Charlotte Perelli (1999), Conchita Wurst (2014), and Carola (1992).

It was a bit of a let-down.

A more dynamic interval performance came from two-time Eurovision winner Loreen, who played her new single Forever in a futuristic, Barbarella-inspired set.

And Blue Swede frontman Björn Skifs opened the show with Hooked On A Feeling, the first ever Swedish song to reach number one in America.

Nemo wowed audiences with their lithe and athletic performance, singing an operatic falsetto while balancing perilously on a spinning turntable.

Their song, The Code, was a deeply personal account of the struggle to accept their non-binary identity.

In the lyrics, they sang: “Somewhere between the zeroes and the ones / That’s where I found my kingdom come.”

The victory represents a big moment for the LGBTQ community which has, for a long time, treated Eurovision as a safe haven.

Last year’s winner Loreen, who handed the crystal trophy to Nemo on Saturday, recently told the BBC how important that support had been to her.

“Eurovision is a community that has an acceptance for diversity [and] different ways of being.

“It’s a very accepting and loving space. And it’s us who are creating it, through creativity.”

Bambie Thug, who is also non-binary, rushed over to Nemo after their victory and handed over a hand-crafted crown, which they wore for their final performance.
