The competition, organised by the International Tennis Federation (ITF) and sponsored by BNP Paribas  involves 16 boys' teams and a similar number of  girls' teams at the at the National Tennis Center and Folyondar Vasas Sport es Tanc center.

The competition is now in its 33rd year having been launched in 1985 as the "World Youth Cup" and a tournament for 16 and under. 

In 2002 the ITF re-branded the boys competition as part of a new partnership with BNP Paribas to "Junior Davis Cup by BNP Paribas". 

The girls' competition was also changed to "Junior Fed Cup by BNP Paribas" in 2005. 

A total of 180 teams from 102 countries took part in  this year's regional qualifying event, with 30 joining the boys and girls from hosts Hungary in the Finals.

Russia and Poland won the 2016 Junior Davis Cup and Junior Fed Cup titles respectively. 

They were also held in Budapest.

“It’s so exciting," 16-year-old Timofey Skatov, the sole remaining member of the Russia team that defeated Canada to win the Junior Davis Cup title last year, said. 

"We’re gonna protect the title from last year and I think it’s going to be very interesting."

The Russian boys return to Budapest to defend their title, but the Polish girls failed to qualify.

Since the launch of the event in 1985, many of the world’s leading names have taken part in the competition, including current stars Roger Federer, Rafael Nadal, Novak Djokovic, Angelique Kerber, Simona Halep, and Agnieszka Radwanska.

The Finals see boys' and girls' teams divided into four groups of four, competing on a round-robin basis, with the top two teams in each group qualifying for the quarter-finals.

Last year saw the ITF announce that Budapest would host the event for three successive years, beginning in 2016.
