Began her 2021–2024 term as federal deputy in the Congress of Mexico on September 1, 2021.
On September 1, 2021, Eufrosina Cruz began a new term as a federal deputy in the Congress of Mexico, marking her return to national legislative office for the 2021–2024 term. This term followed her earlier federal service from 2012 to 2015, during which she had chaired the Commission of Indigenous Peoples and championed the landmark 2014 constitutional suffrage reform.
Her renewed presence in the federal Congress allowed her to continue pressing for stronger legal protections for indigenous women and children, building on decades of advocacy that began with her own personal experience of political exclusion in her hometown of Santa María Quiegolani. During this term, she would go on to spearhead one of her most significant legislative achievements: the 2023 reform criminalizing child marriage under the Federal Penal Code.
Her continued election to federal office demonstrated the durability of her political career and the broad support she commanded as a voice for indigenous and women's rights within Mexican national politics. It also reflected the ongoing relevance of her core mission — ensuring indigenous women's full and equal participation in Mexican civic and political life — nearly fifteen years after she first began her fight following the annulment of her hometown mayoral victory.
