Western Horseriding vs English Horseriding - the differences between the 2 styles of horseriding.

I'm not sure how things are done in the US. Good question tho.

Portuguese Horse Breeds.
Iberian Greats
Portugal isn’t a large country and its horse breeding is closely tied with that of Spain. Their breeds clearly share common ancestors as they both display the noble Iberian traits. Both the Alter Real & the Lusitano are good examples of this with their stout composition and grandiose demeanor.

Lusitano
Horses were known to humans on what is now the Iberian Peninsula as far back as 25,000 to 20,000 BC, as shown by cave paintings in the area.[1] Among the local wild horses originally used by humans were the probable ancestors of the modern Lusitano, as studies comparing ancient and modern horse DNA indicate that the modern "Lusitano C" group contains maternal lineages also present in wild Iberian horses from the Early Neolithic period.[2] These ancient horses were used for war, with clear evidence of their use by Phoenicians around 1100 BC and Celts around 600 BC.[1] It is believed that these invaders also brought horses with them, contributing outside blood to the ancestry of the modern Iberian breeds.[2] By 800 BC, the alliance known as Celtiberians had been formed by the Iberians and Celts, and from this point on the horses bred in this area were renowned as war horses. Xenophon, writing around 370 BC, admired the advanced horsemanship and riding techniques used by Iberian horsemen in war, made possible in part by their agile horses. Legend claimed that mares of the area were sired by the wind (hence their amazing swiftness, passed onto their foals), and one modern hypothesis suggests that the bond between Iberian humans and horses was the initial inspiration for the centaur,[1] which was believed to come from the area of the Tagus River. Later invasions into the area by Carthaginians and Romans resulted in these civilizations establishing stud farms that bred cavalry horses for the Roman army from local stock.[1]




Garrano
The Garrano, sometimes called the Minho, is an ancient breed from the north of Portugal. The Garrano mainly lives in the fertile regions of Minho and Trás-os-Montes e Alto Douro.

Genetically related to other Atlantic horse breeds, it is generally believed that the Garrano is one of the ancestors to the Galician Pony and the Pottok pony.



Sorraia
The relationship between the Sorraia and other breeds remains largely undetermined, as is its relationship to the wild horse subspecies, the Tarpan and the Przewalski's Horse. The Sorraia originally developed in the southern part of the Iberian peninsula.[8] d'Andrade hypothesized that the Sorraia would be the ancestor of the Southern Iberian breeds.[9] Morphologically, scientists place the Sorraia as closely related to the Gallego and the Asturcon,[10] but genetic studies using mitochondrial DNA show that the Sorraia forms a cluster that is largely separated from most Iberian breeds.[11][12][13][14] Some evidence links this cluster with Konik and domestic Mongolian horses.[12] At the same time, one of the maternal lineages is shared with the Lusitano.[15] Genetic evidence[11] has not supported an hypothesis that the Sorraia is related to the Barb horse, an African breed introduced to Iberia by the Moors.[16]

Multiple authors have suggested that the Sorraia might be a descendant of the Tarpan based on shared morphological features, principally the typical color of its coat.[2][3][17] Other authors simply state that the Sorraia has "evident primitive characteristics", although they do not refer to a specific ancestor.[5] However, there have been no genetic studies comparing the Sorraia with the Tarpan, and similarity of external morphology is an unreliable measure of relatedness.[11]

Genetic studies to date have been inconclusive about the closest relative of the Sorraia. On one hand, studies using mitochondrial DNA showed a relationship with the Przewalski's Horse,[12][13][14] in that Przewalski's Horse has a unique haplotype (A2) not found in domestic horses, which differs by just one single nucleotide from one of the major Sorraia haplotypes (JSO41, later A7). In comparison, genetic distances within the domestic horse are as large as 11 nucleotide differences.[12][13][14] However, this relationship with the Przewalski's Horse was contradicted in another study using microsatellite data that showed that the genetic distance between the Prewalski's Horse and the Sorraia was the largest.[18] Such conflicting results can arise when a population passes through a genetic bottleneck, and evidence suggests that the Sorraia, among other rare breeds, has recently passed through a bottleneck,[12] effectively obscuring the position of this breed in the family tree of the domestic horse. Thus, the morphological, physiological, and cultural characteristics of the Sorraia are the subject of continued study to better understand the relationship between various Iberian horse breeds and wild horse subspecies.






There are more 5 or 6 but they are not pure anymore.Like the Alter-Anglo.Mix of Alter-Real+Anglo horse.
