In the early period of the Imperium this was a simple process, a straightforward pledge to provide a certain number of troops and to fight in person. This was seen to be too inflexible because as the Imperium grew, the differing numbers of troops provided made poor use of some planets' populations and on others too high a proportion of the population was sent to war, leaving the planet sorely short of labour.

Sometimes, this action can lead to The tithe is also a depleted defence force until percentage of the men return or more are recruitedplanet's produce. Most tithes are regular obligations, while others are demanded when specific circumstances are met.
