Bayanihan is a concept in the Philippines that refers to a spirit of communal unity and cooperation, usually centered on members coming together to help one of their own. It has its origins in rural towns, where members help a family move to a new place by volunteering to physically transport the entire house to a specific location. This is usually followed by a celebration to express gratitude to the volunteers.
Bayanihan persists to this day in both rural and urban communities, especially in slums. Examples include raising money to help one member pay for medical treatment, helping new arrivals get situated, and rebuilding any homes lost to natural disaster. Even the poorest citizens manage to pool their resources and capital together to ensure one of their own is looked after.
In its most dramatic manifestation, bayanihan was utilized in the capital city of Manila to form a successful grassroots movement, which influenced the government to help establish better housing and infrastructure for poorer residents.
