Ricardo Marcenas was born in America, but because his family travelled a lot, he spent his childhood in several countries. As an adult, he entered politics and eventually became the first Prime Minister of the Earth Federation, with the support of the liberal faction.
As Prime Minister, Marcenas was instrumental in the drafting of the Charter of the Universal Century. Marcenas personally proposed Article 15: "In the future, should the emergence of a new space-adapted human race be confirmed, the Earth Federation shall give priority to involving them in the administration of the government." Some speculated this article was meant to atone for migrating much of Earth's population into space.
With the Charter signed, Marcenas unveiled it and inaugurated the Universal Century from his official residence, the Laplace colony. But his speech was interrupted when terrorists, including a young Syam Vist, destroyed the colony, sucking Marcenas and everyone else present into space. This became known as the "Laplace terror incident". The incident made Marcenas into a martyr for the Earth Federation, and the posthumous founder of a political dynasty; his son George would go on to become the third prime minister, and his grandson Ronan would become an important member of the Central Council.
In truth, however, the terrorist plot was orchestrated by George and other right-wing extremists who opposed his leadership and rapprochement with the space colonies. Without Ricardo as leader, article 15 was quietly buried; when the Charter was reintroduced, article 15 was omitted. The original monument to the Charter, with article 15 intact, would later be recovered and become known as Laplace's Box.
