Lucca was the capital but Pisa was the most important city, as in the middle of 10th century Liutprand of Cremona, bishop of Cremona, called Pisa Tusciae provinciae caput ("capital of the province of Tuscia"), and a century later, the marquis of Tuscia was commonly referred to as "marquis of Pisa".
Lucca var hovedstad, men Pisa var den vigtigste by, og i midten af 900-tallet kaldte Liutprand af Cremona, biskop af Cremona, Pisa for Tusciae provinciae caput ("hovedstad for provinsen Toscana"), og et århundrede senere blev marquisen af Toscana ofte omtalt som "marquis af Pisa".
