Bayanihan is an example of an old tradition that expresses the spirit of unity.

A pagta too expresses the spirit of unity between former warring tribes. By entering into pagta, the parties thereto intend to unify themselves for their mutual aid and protection. Breach thereof detroys the unity and results to division and contention.

Here are sample pictures of tribal weapons used in case there are contentions.
