As a result, Eufemiano Fuentes Díaz, president of Marino CF, went to a meeting in Madrid to change the legislation of contracts to a minimum of four years.

The purpose of this proposal was to present a compelling case to the RFEF for allowing the Canary Islands to participate in national competitions, enabling Canarian footballers to compete without relocating to the Spanish mainland.

Gran Canaria, Atlético and Arenas promptly agreed to the proposal due to their finances whilst Marino and Victoria remained wary of the repercussions it could have on the club and its fans.

[3][4][5] Don José Del Río Amor, of legal age and from this neighborhood, acting as President of the Management Commission of the Club "Unión Deportiva Las Palmas" to that Excma.

[4] The acceptance allowed the merger of Arenas Club and CD Gran Canaria, both of whom gave up their headquarters and trophies, to form under the name Unión Deportiva Las Palmas as the first phase for total integration.

[3][4] On 16 August 1949, the Fusion Presentation had their last meeting where after coming in contact with Marino and Victoria stated the clubs would not merge as of yet due to difficult financial situation.

After a successful meeting in which all five clubs unanimously agreed towards the final proposition presented by Monroy, Unión Deportiva Las Palmas was officially established at 8 p.m. on 22 August 1949.

Fortunately, Imperial de Murcia, who sat third in the table, also faced defeat, securing Las Palmas' certified promotion to the Second Division.

[20] In the club's first match of the season, Las Palmas would lose 4–1 to Real Madrid at the newly inaugurated Insular Stadium on 9 September 1951.

[21] The following games saw defeat to Celta (5–2), Sevilla (5–0) and Deportivo La Coruña (3–1) before the club earned their first point to Racing Santandar after a 1–1 draw on 23 September 1951.

[26][27] On 26 March 1952, Las Palmas played Millonarios de Bogotá in a match that contained the likes of Alfredo Di Stéfano.

The Colombian team at the time was considered the best in South America and had remained undefeated against the likes of Porto, Real Madrid, Sevilla and Valencia during their tour in Europe.

[32] Los Amarillos drew both matches they played against Tenerife, the last being on 25 April 1954 where a goalless draw led to Las Palmas' promotion at the Santa Cruz Stadium.

[36] According to Marcial Sánchez, a player who signed from Real Murcia in the 1954–55 season,[37] the club briefly shared a spot in the top three of the league table with Barcelona at one point.

However, due to the losses of key players, including captain Juan Beltrán and Marcial himself, the club's form deteriorated as the season progressed.

[38] Beltrán, in particular, was a highly respected captain and nicknamed by the fans as "El del pañuelo en la frente" (The one with the handkerchief on his forehead).

[46] The most notable match under Molowny's management was on 9 February 1958 when Las Palmas held a clash against Atletico Madrid at the Insular Stadium.

[54] During the season, Vicente Gonzalez Sosa became the first international youth player for Las Palmas, making four appearances for the Spain national under-18 team between March and April 1960.

Managed by Vicente Dauder, they finished third in 1967–68 behind Real Madrid and FC Barcelona, and four club players made the Spain squad which hosted and won the UEFA Euro 1964 tournament; the following season the team fared even better and only lost the league to Real Madrid, and thus qualified for European competition for the first time in its history, appearing in the 1969–70 Inter-Cities Fairs Cup and being knocked out in the first round by Germany's Hertha BSC (0–0 home draw, 0–1 away loss).

The next season, French coach Pierre Sinibaldi led the club to the fifth place, with subsequent qualification for the UEFA Cup: after disposing of Torino F.C.

and ŠK Slovan Bratislava, the Spaniards bowed out to Dutch club FC Twente; at the end of 1974–75 another team player, Tonono – a defender who played with Guedes – died of a liver infection.

Las Palmas' third appearance in European competition came with the 1977–78 UEFA Cup, where they defeated FK Sloboda Tuzla of Yugoslavia in the first round before falling to the English side Ipswich Town.

On 3 October 2001 the side managed a 4–2 home win against Real Madrid, with youth product Rubén Castro scoring two goals for the hosts, but the season ended nonetheless in relegation.

On 27 May 2023, Las Palmas achieved promotion to the first division by sealing a 2nd position in the table, respectively, on the very last match day of the season, after spending five years in the second tier.

The current land in Barranco Seco was acquired by UD Las Palmas during the 1960s by the efforts of then club director Manuel Betancor.

It was designed by architect Juan Palop-Casado,[59] who assured that the construction of this project was "an attempt that has been made to build with the greatest possible sustainability".

[61] Being only the first phase of the entire sports city project, the club invested 22.5 million euros of its own funds to carry out the construction works of the current facilities.

The Ciudad Deportiva is home to 3 regular size training pitches:[63] Note: Flags indicate national team as defined under FIFA eligibility rules; some limited exceptions apply.
