The 1986-87 season will be remembered as a turning point in Eibar's history, a club that has managed to overcome challenges and build its identity over the years. At that time, Eibar was competing in the Regional Preferente, a category that, while less known, was home to many historic teams in Basque football.

The road to promotion was not easy. With a squad made up mostly of local players, Eibar faced rivals with more resources and experience. However, the determination and fighting spirit of the players were key factors in the season's success. The armeros, led by their coach at the time, implemented a playing philosophy based on collective effort and solidarity on the pitch.

As the season progressed, Eibar began to gain notoriety. The fans, who had always supported the team, became more numerous and vocal at the Estadio Municipal de Ipurúa. Each victory was celebrated as if it were a title, and each loss became an opportunity to learn and improve. The bond between the team and its supporters grew stronger with each match, creating a unique atmosphere that would become the essence of the club.

The climax came on the final day of the season. With everything at stake, Eibar needed a victory to secure their promotion to the Tercera División. The team took to the field with palpable determination, knowing that every pass, every shot, and every play counted. The overwhelming joy that followed the final whistle not only marked a promotion but symbolized the beginning of a new era for the club.

The 1986-87 season was not just a success in terms of promotion; it also laid the groundwork for Eibar's future development. Over the years, the club continued to grow, moving through different categories and eventually reaching La Liga. The story of that promotion has become a source of inspiration for generations of players and fans, reminding us that with hard work and unity, any goal is achievable.

Today, as we look back on that historic season, we can see how those moments forged Eibar's character. The identity of the armeros, shaped by the struggle and passion of their supporters, remains alive in every match, every season, and every challenge the club faces. The promotion of 1986-87 was not just a sporting achievement; it was the beginning of a story still being written in the hearts of Eibar's fans.
