Among those at the annual event in Stone Cross, in West Bromwich, were veterans from the Armed Forces and the Royal British Legion.
Before the parade started yesterday, a minute's silence was held in memory of all those who lost their lives in the First World War.
It was followed by a rendition of 'Jerusalem' and 'God Save The Queen' before the crowds – many waving flags – set off on a march around the streets.
The march began in Westminster Road before a sea of red and white made their way to Dartmouth Park.
Houses along the route were decorated in the colours of St George with organisers estimating as many as 15,000 took part in the celebrations.
Among those at the parade was Jacqui Johnson, aged 57, from West Bromwich. She said: "I come every year and it's good to see the community celebrating. There's always a really good spirit and everyone enjoys themselves."
Her friend Claire Blakemore, aged 40, from The Woods Estate, added: "It's organised really well and it's good to see people out and taking pride in their country and their history."
The parade has been going for 17 years and is funded privately from donations from the community.
It has grown year by year and attracts participants from across the country.
Organiser Mark Cowles, 45, said: "This a parade funded by the people for the people.
"It is something to celebrate our heritage and being proud to be English. It is the biggest parade in the country and we get people from London and from up north coming here.
"It has been a fantastic day and you can see what it means to the community when you're marching and there are old women with a tear in their eye as we pass them."
