Harlequins director of rugby Conor O'Shea says contributing to the success of the England team is the cornerstone of the club's philosophy.
Quins had six players on England's tour of New Zealand in June, while Marland Yarde joined the club after the trip.
"We provide players for England and a style of play that people have tried to emulate over the last number of years," O'Shea told BBC London 94.9.
"This club is about success for Quins and success for England."
He added: "It would be a pretty sad world if that is something that is not lauded."
|Quins' England contingent:|
|Chris Robshaw (flanker, 28 caps, England captain since 2012)|
|Joe Marler (prop forward, Quins captain, 22 caps)|
|Mike Brown (full-back, 29 caps)|
|Marland Yarde (wing, five caps)|
|Danny Care (scrum-half, 48 caps)|
Quins flanker Chris Robshaw has been England captain since 2012, while prop Joe Marler, scrum-half Danny Care and full-back Mike Brown are all integral parts of Stuart Lancaster's national team set-up.
The south-west London side won three trophies in three years between 2011 and 2013, adding the Amlin Challenge Cup and the LV= Cup to their 2012 Premiership crown.
O'Shea said their previous success and seeing their players attain international recognition has given the club "belief through knowledge".
"We have been there, done it, hit adverse times and come out the other side," the Irishman said.
"We have to make sure we evolve to keep ahead, because there is no doubt that teams are playing more and more like we have.
"We have belief through winning and belief through the players we provide for England. I am looking forward to some of the other players that are young and developing, like Charlie Matthews, Will Collier and Kyle Sinckler, playing for England in the future."
Harlequins have won three and lost three Premiership matches this season, and O'Shea has already warned that his side should not be written off despite their mixed start to the season.
"People over-react but we leave that to people on the outside," he said.
"We will react in an emotional and analytical way and make sure we are focused on what our next job is.
"We've had four years of relative success but we live in a world which is very immediate and the response is very definitive. I'm not saying that everything said isn't right - far from it.
"There is a lot of white noise out there that is irrelevant. It's sifting through that and focusing on what your job is and how you do it best."
The Twickenham Stoop side begin their European Rugby Champions Cup campaign on Friday, against French side Castres.
"We are against a good side who have had a difficult start as well," O'Shea said.
"This is what you play for and our players love one-off games. It suits what they call a 'one shot, one kill' mentality.
"There is no pressure on the players, who will go out and play the Quins way. If it is good enough, it is good enough."
