In most cases, 'El Rey' is not based on actual events. It's more of a fictional narrative crafted for entertainment purposes. The plot and characters might be inspired by various elements but not by real-life happenings.
Since I don't know the exact 'el rey based on a true story', I can only guess. It could be that 'el rey' was a historical or contemporary figure. If it's a historical account, it might detail the political, social or cultural environment of the time. For example, if he was a king in a certain era, it could tell about the wars he fought, the alliances he made, and how he influenced the development of his kingdom. It could also explore his personal life, his family, and his beliefs.
Well, the 'El Tapatio Family' in Mexican context could have a story full of rich cultural aspects. They might have been farmers growing traditional Mexican crops like corn or beans. Their family story could be about how they faced challenges in farming, like dealing with droughts or pests. And also about how they maintained their family unity through tough times. They may have specific family celebrations that are unique to them, which are influenced by the broader Mexican culture. For instance, their celebration of Day of the Dead might have special family - centered traditions that have been carried on for generations.
