Harvests in Sweden before the agrarian revolution: Öland

Grain tithe (Swe: Spannmålstiondet) has often been used as an indicator of crop development. It was a tax based in the principle of one-tenth of the harvest. This database is based on the accounts of the Crown's share of the tithe for Sweden in present-day borders excluding Scania. The databases relate to the period from and including 1665, when the volume measures were uniform in the country, until the tithe was a fixed tax without further linked to harvests. The transition to the tenth occurred successively in different provinces and was essentially completed by the mid-1700s.谷物什一税（Grain tithe，瑞典语：Spannmålstiondet）常被用作作物收成情况的指示性指标。该税种以收获物的十分之一为计税依据。本数据集基于瑞典现今疆域（不含斯科讷省）的王室什一税份额账簿，涵盖的时期自1665年（含该年）起——彼时瑞典全国已统一容量计量单位——直至什一税演变为不再与收成挂钩的固定税种。该税制向什一税的转换在各省份逐步推进，并于18世纪中期基本完成。
