Inside the 25,000-seater Estadio Hidalgo in east-central Mexico, fans unfurl a tifo featuring a miner.

In one hand he wields a pickaxe and the other a pastry with a distinctly crimped edge.

He is flanked by two flags, both the same - black with a white cross.

To anyone with a knowledge of the United Kingdom's southernmost county, this figure is instantly recognisable as Cornish.

The fans of CF Pachuca, widely recognised as Mexico's first football club, are paying tribute to their roots.

They are celebrating the story of how miners from Cornwall played their part in introducing the game to what has become one of the world's most passionate footballing nations, and one of this year's World Cup co-hosts.

The transatlantic connection between Hidalgo and Cornwall starts all the way back in 1824.

Mexico's mining sector, which had been the bedrock of the country's economic success, was in ruins after a decade-long war that resulted in independence from Spain.

Its plight caught the eye of a mining engineer called John Taylor, who had been investing in Cornish mining with great success, particularly in the village of Gwennap.

"He had taken a group of failing and flooded mines and turned them into a success and he looked at the mines of Real del Monte and thought, 'I can do the same there'," Cornish mining migration specialist Dr Sharron Schwartz tells BBC Sport.

His involvement led to hundreds of Cornishmen going back and forth between Cornwall and Hidalgo in the coming decades.

With this migration came a sharing of ideas, culture - and, of course, sport.

The first mention of a football team in Pachuca came in 1892, with a local newspaper article reporting on a reorganisation of the team due to a "schism".

"There had been a rift between those in Pachuca and 'the mountain men', meaning those in Real del Monte.

"When I read this I laughed, I thought 'how Cornish'. The Cornish love a schism.

"They were told to get their acts together and make their team stronger."

In 1895, there was a meeting held by Rule that led to the decision to amalgamate the Pachuca Cricket Club, the Pachuca Football Club and the Velasco Cricket Club to create a stronger entity.

Thus was formed Pachuca Athletic Club.

Rule donated a piece of land near his hacienda for the club to host games, on the condition that games would not be played on a Sunday because of his Methodist beliefs.

By 1902, other clubs had started to pop up in areas such as Orizaba in Veracruz.

To this day Orizaba contest the view that Pachuca were the first club in Mexico, and claim that title as their own.

These two clubs, as well three others, came together to create the first recognised football league in Mexico, the Liga Mexicana de Football Amateur Association.

Orizaba won the first league title in 1902, with Pachuca having some success of their own in the early seasons, winning the title in 1904-05.

It was not just the mining men enjoying the football on the pitch - Cornish women were also a key part of the matchday spectacle.

"They loved to turn out [for matches] and often wore the club colours," says Dr Schwartz.

"The first reference to pasties being consumed [in Mexico] was when play stopped in a cricket match. I can imagine those were cooked by the Cornish ladies."

Pasties were an essential for miners at the time, with their thick crust acting as a 'handle' for dirty hands and pastry tough enough to survive being dropped down a mineshaft.
